but like any big city, there is a constant fight against crime and a landmark of that battle is just outside downtown. bexar county jail is a modern fortress that houses approximately 3,500 male and female inmates. most have only been charged with crimes and are awaiting trial for the resolution of their cases. >> we're very regulated on how we treat inmates. even though they're incarcerated, they still have rights. we realize we're here not to punish anyone but hold them. >> holding inmates is never a simple proposition, especially when they don't want to be held. >> a lot of the gang members, they've got all that time, you

know, to think of different games they can play with the officers because they're trying to create a reputation for themselves that they're not to be messed with. >> i'm easy to get along with, once somebody disrespects me or something, we're going to take care of business. >> jose hidalgo is a member of what's described as one of the most notorious gangs. he describes the gang more as a fellowship. >> they're in prison on the make sure the home boys make it safe back to our families and to make sure if one of our home boys need something, we're going to be there. >> since the age of 14, hidalgo has spent most of his life incarcerated. he's been in jail for the past three years charged with 16 crimes.

>> aiding, robbery, possession, daily conduct, dwu, assault by injury. i've got the whole list in my cell. >> hidalgo has pleaded not guilty to all charges and also those charges he picked up inside the jail. >> two assaults on public servants and two arsons. i picked up one last week. i'm awaiting to get indicted on that. his latest assault on staff occurred after a rare period of good behavior. >> most of the time that hidalgo has been in our facility he's been housed and grouped alone because we found when he's housed with other inmates he

tends to rub off on other inmates. instead of dealing with one, we're dealing with many. although recently for the past few months he's been out of trouble, cooperative, behaving, and one thing he's cree quested is a cell mate. after a careful review we allowed him to have a cell mate. >> his cell mate is waiting to transfer to prison to serve a five-year sentence. >> i roll pretty good but hang around with wrong people. a good kid went wrong, huh? >> on the second day they were housed with each other the two inmates showed up on staff's radar. >> they were disruptive across the day, and when they did chow, he stuck his arm out the tray slot, wouldn't bring it back in so we could close it. >> after meal service they decided to check his cell for contraband. >> and about the time the door opened i don't remember who was on which bunk but both stood up

and came toward the door and stood side by side creating a barrier. >> he wanted to search the cell and we didn't try to let him in. >> we were like, hey, we want to come in and search for contraband and they're like no, you can't come in here. >> they said get against the wall. i said for what. he said to shake you down. i said you're not going to shake you down. >> i thought, at first there's something in the cell, and i realized, no, there's going to be a fight. as he tried to pass between the inmates, he hit him. >> he hit him with his right hand. >> i defended myself and i went off him. we were fighting. the officer, he was on the floor repeatedly hitting my cellie. >> guerrero then jumped on the officer's back. >> apparently he put him in a choke hold with his right and banged on his head with his left.

>> officer lighty came to his partner's defense. >> i came in, grabbed guerrero by his arms, tried to pull him off. i wrestled with him a little bit. >> i'm getting at these other men. blood everywhere. >> officers inside the housing unit security home room witnessed the fight. >> the team arrested and secured hidalgo. >> they came and dropped their knee on me, boom, split my chin, caused me to get stitches. blood's coming up. i was lying in my blood. >> as hidalgo and guerrero were escorted by the team to medical, another home member jeremy gonzalez witnessed the possession. >> i wasn't going to let it

ride, you know what i'm saying? i kind of let my anger get the best of me too and popped out with the shank. >> he defeated the device, opened the cell door and was holding a piece of 7-inch metal. >> it was made out of a top blade of a squeegee. >> unfortunately by the time he decided how to pop the cell door, they had left the unit. >> he came running out in the day room and thought everybody was fighting. he got to right about here and then he realized that, you know, he was a day late for the party. >> there was four laws down there, sergeant, lieutenant, corporal, and regular officer. >> and he started to get real

nervous because, you know, he had no backup, he's over there with a weapon in a secured facility. with gonzalez out, they're called back to assist. >> i'm not stupid, you know what i mean. i laid it down real quick, threw the shank away from me. chilled out real quick. >> he threw the knife on the ground, not at the officer. it was very gently thrown to the floor and he laid down on the floor. >> luckily no one was hurt. what does scare us is he had the shank and we wonder what would have happened if he was close enough. it could have easily have gone bad as it went good. >> all three inmates involved in the incident were moved to single-man cells and were given new felony charges. for gonzalez, the new charge can carry especially serious consequences. he is awaiting trial on a murder

charge. he has pled not guilty. >> i just wish i hadn't done that because it's going be like a domino effect with my other case, you know what i mean? just that little case right there is going to get me bad. they're going to see me as a threat to society coming out with shanks in jail, you know that? so that's probably going to sting me, you know what i mean? coming up -- backed up toilets flood a housing unit and jeremy gonzalez faces off with a special response team. >> but first -- >> i had him on account of a pencil. i'm like, you move, and i'll poke your eye out. >> one of the most feared female inmates in bexar county.

peers have less than ideal hygiene, many inmates at san

antonio's bexar county jail do as much as they can to make their cells as sanitary as possible. >> can you imagine the opposite, it is not. >> diaz, who's awaiting trial and pled not guilty to burglary, theft and cocaine possession says cleanliness can lead to conflict. >> that's a big part of being locked up. you know, there's people who get dropped, beat up, because they don't keep things clean. >> diaz's cell mate, marcelo cardenas who is convicted of aggravated assault and is awaiting to be transferred to prison to begin a six-year sentence is happy to indulge him. >> he jokes i have an obsessive compulsive disorder. >> which is fine for me, right? >> well, i'm not a germaphobe, but being in prison might make some people anal. >> that's why we keep a towel or

shirt to keep the dust out because when people blow by, it blows in dust. for all the people who think we live in filth, on the contrary, we probably have a cell cleaner than most people's houses. >> while the jail lets most use cleaning supplies, others like erica hayward gets only minimal. >> she's getting pine b, only a little mixed with water and two sanitary pads to clean her cell. >> let me know when you're done it's a yellow clean solution they give us. i basically use it on my floor, the mattress, the toilet. they won't give me a broom because i had an incident with one of the guards because we had a confrontation. now they won't give me the broom. >> we used to give her the broom

but she decided she was going to jab an officer through the tray slot with a broom. >> in the three months she's been in bexar county, she's attacked staff and others. she's assigned to a cell 23 hours a day. it is often a noisy disruptive place. >> some are very hostile, very aggressive. we do have to be very careful because one woman to another they can just snap at you. >> haywood has done time in jail on prior convictions. her latest arrest came after a fight with a bank security guard who ordered her to get off the telephone. >> if he had approached me differently, i probably wouldn't have did that, but he was embarrassing me. we started going off each other. he was in my face, i was in his face, he reached in to grab me, bam, i took him down.

i had him on account of a pencil. i said, if you move, i'm going to poke your eye out. he did not move. >> haywood is yet to be charged with aggravated assault and bodily injury. she admits it's hard to control her temper. >> you tell yourself you can control it. you tell yourself i can control it, i'm not going to hurt nobody, but when it actually comes time to do it, it's like, bam, just hit somebody. it's like a reflex. they might say one wrong word to you, bam, you hit them. >> officer laura was also a victim of haywood's temper. >> the day that erica assaulted me i was just doing my observation rounds and passing out mail like i would normally do.

>> i told them in the hallway i could feel the anxiety coming on, i knew an attack was coming on, i knew i was going to hurt somebody. >> erica was out in her day room and at that time she was only wearing leg irons. her hands were totally free. >> here's the lady passing out mail and i was like why you trying to confront me. she was like, mm-hmm, mm-hmm. >> she took a swing at me, scratched my face, and it was on. we went toe to toe. i did punch her in the face. i punched her in the body. all i wanted her to do is quit charging me. she continued charging me. >> then i started fighting her back. next thing i know, here comes the sert team. >> i was abe to move out of the way. all i saw was a sert officer with a taser and they tased her. >> they shot me. i had a probe, like a long string with a pin look like a

dart stuck into my body. they got me mostly in the shoulder area, i think, and i could feel myself going out. >> stop resisting, haywood. >> because the pain is so excruciating, all you could do is take that pain, take that pain, take that pain. my family always taught me don't let people disrespect you. we just like that. we're very reactive people. this is the way i grew up. people look she's violent. i'm nowhere near what my family has raised me to be and they have no idea. that's it. >> [ bleep ]. >> i'm mild. very mild compared to some people. >> [ bleep ]. coming up -- >> i threw some bodily fluids and things.

as in other correctional facilities, tattooing is not allowed in bexar county jail. violators could get up to 60 days in segregation or even face criminal charges but the demand for tattoos on the inside are so great there are always inmate tattoo artists willing to take the risk for pay out or other forms of commissary. they make ingenious tattoo guns. by assembling the parts of other items they are permitted to possess. staff are constantly on the lookout for them. >> i was patting him down, down in his crotch area, felt the -- you know, the bulge, i asked him what it is and he just pulled it out, opened it up. a catch like this is pretty rare. >> was a good catch, man.

>> right here is from inside of a light, a staple. this is the copper wire that came from inside of the hair clippers and two checker pieces to hold it together. these guys know what they're doing. another inmate marcelo cardenas is not a tattoo artist he has a reputation for crafting tattoo guns. >> i rent the gun. it goes if $35. $25 or $35. >> because he's leaving the jail any day to start his six-year sentence for assault, he's demonstrated how it's done. >> right now it's not like i really care about it. if they rub me out, i'm going to leave before they reprimand on me. >> cardenas starts with wire scavenged from some electric hair clippers. he winds the wire around the screw to make a crude election

-- electric magnet but he also needs a filter magnet pilfered from a phone or speaker. >> when you put it on here, it bounces with the cycles of electricity. >> the needle is made from a staple attached to a q-tip shaft. >> and then you use soft string to tie it up. that's pretty much how you do it. when he pounds, he pushes the needle. >> several other bexar county inmates also make their tattoo guns and the source of their knowledge could very well spring from just one man, jose hidalgo. >> early on in his incarceration he was teaching people how to create the tattoo rigs and as a result they were destroying county property. >> when we're in the cell 23

hours a day, we get creative in breaking lights to get the wire. we burn grease to make the ink. >> even though we pulled him out, the knowledge he gave them is still something we're combatting today because inmates are constantly making rigs and constantly tearing apart light fixtures and it's something that he started. >> hidalgo has also been on the receiving end of the jailhouse tattoo trade. >> when hidalgo first came into the facility, he didn't have anywheres as near as many tattoos he has now. most he has received he's received within our facility and he's very proud of his tattoos. >> on top of my eyebrows it says made in the hood. i was made in the hood. that's the reason for that. 227.

i asked him why and he said no reason. >> a major disruption prompted the response team to take action. ogressive's "name your price" tool? i guess you can tell them how much you want to pay and it gives you a range of options to choose from. huh? i'm looking at it right now. oh, yeah? yeah. what's the... guest room situation? the "name your price" tool, making the world a little more progressive.

>> here's what's happening this hour. australian officials are expected to hold a news conference any moment to update the search for a missing malaysia jan airline flight. it comes after a chinese ship report finding a pulse in the indian ocean. authors live pictures. experts say it's consistent with the plane's black box but caution the report about the pulse has not been verified. chinese plane said i found debris in the same area. now back to "lockup" for you. due to mature subject matter, viewer discretion is advised.

despite staff's best efforts to stop them, some inmates at san antonio's bexar county jail still find ways to illegally tattoo each other, but if staff can't catch every tattoo, they can at least document them and add them to their intelligence base. >> tatoos are the most common nonverbal forms of communication in identifying gang affiliation. gang members love to put their gang somewhere visibly on their body so rival gang members or their own gang members can identify them as are they friend or foe. and we train our class officers to look for these identifiers and if they can't get the gang member to self admit, then we refer to the gang officers and we look at the tattoos. aside from their tattoos, we'll look at their history and decide if they have a history of gang activity, strong-arming in the units, group assaults, things of that kind of nature. in conjunction with that, we can

go ahead and establish whether or not we think the guy's a gang member. >> raymond diaz is up front about his gang-related tattoos. >> the stuff i got on me, a lot of it is gang related. they call them like stamps, you know. everything was done behind bars with a staple. we don't use fancy needles and all that. the main part on my chest, it's blast, dongo blast. one of the biggest prison gangs in texas. i chose to put it in big letters on my chest because when i get to a prison unit the first thing i do is take off my shirt and it's clearly visible. if someone has a problem with me, they're going to let it be known. >> diaz is also a tattoo artist and says he has applied many himself. most are gang related but one is a fan tribute. >> which is my taylor swift.

i did her for my own personal gratification. i don't know what it is about her but the first time i heard her voice, i was locked up. i would listen to her music and she's got a cute country voice. it soothed me. no matter what's going on, it soothed me, fights going on, buildings burning down, but if i'm listening to taylor swift, i'm relaxed. >> but it seems no melody can quiet the outbursts. it houses members of the jail's largest gang. >> usually they'll call a disruption if they're upset or want to gain attention. mostly they're kicking the doors. one starts screaming. some days it's worse than others. they're young, rambunctious, they have nothing better to do, so that's the way they make their noise. you know, everybody thinks that

this job is such a gravy job and such an easy job. i challenge anybody to come in here and work this job for a week and see if we're overpaid. >> later in the day, the disturbance escalates when one of the inmates starts flooding the unit. >> the guy in 12 unit started flooding his cell. i asked him why. he said for no reason. he's notorious for that. >> the inmate is known to staff. jeremy gonzalez. besides facing charges of murder and aggravated assault, gonzalez just picked up another felony charge after confronting jail officers with a 7-inch-long shank. since arriving he's been sanctioned for several other infractions as well. >> i've been trying to do good for six months straight. i've been trying to chill and get my visits back. get back to my family.

you go through the depression mode and aggravated. >> with within two minutes two others add to the flooding. >> they're utilizing uniforms, whatever they can find by flushing the toilets, causing them to overflow just to be belligerent and disruptive. >> gonzalez's friend says he's not impressed by his actions and that such behavior is now looked down upon by the gang. >> they know we don't do that no more. they know we don't do that. >> how are you doing? >> the special emergency response team or sert is mobilized to restrain the troublemakers. >> the sert team was called in. the system was activated.

>> they will put them in restraints due to destructive behavior, not to harm themselves or anybody else. >> the team begins with gonzalez who submits to their orders but not quietly. >> anyone who is shackled, they'll be shackled every one to two hours and medically evaluated every one to two hours by the medical staff. that is medically to see if there's any cramping, any injury toward the inmate himself. richard lui with msnbc. breaking news. australian officials about to hold a news conference. comes after reports that a chinese ship discovered pulse signals consistent with a black

box. they were reporting that on saturday. they also reported on friday they had detected some signals that were consistent with the pinging sound that comes from the blacks boxes. that frequency of 37.5 kilohertz. >> people on the stage with me today, commodore peter levy, the task force commander. on my left here i have mr. scott constable from the australian safety maritime authority and i have bob armstrong from the australian transportation safety bureau. i called this media conference to provide you with the latest information i have regarding the search for the missing malaysian airlines flight mh-370. as you're aware late yesterday reports surfaced in the chinese

press that the chinese ship had detected electronic pulse signals in the indian ocean. i issued a media release overnight confirming that i had been advised that a series of sounds had been detected by the chinese ship with characteristics consistent with the aircraft black box. additionally, i confirmed a number of white objects which were also sighted on the surface about 90 kilometers from the detection area. i made clear, however, that these signals and the objects could not be verified as being related to missing aircraft at that point in time. that remains the case. i also advised that the australian march tame safety authorities rescue nation center had spoken to the rescue

coordination center in china and asked for any further information that might be relevant. this morning we were contacted by the chinese authorities and advised that the ship had late yesterday afternoon redetected the signals to 90 seconds within just two kilometers of the original detection. this is an important and encouraging lead. but one which i urge you to continue to treat carefully. we are working in a very big ocean and within a very large search area and so far since the aircraft went missing, we've had very few leads which allow us to narrow the search area. obviously we take any reported leads in the search very seriously. that's why today australian air force assets were deployed to

assist in further examining the acoustic signals in the vicinity of where the chinese ship has detected the sounds. hms echo and australian defense vessel ocean shield are also being directed to join the chinese ship as expeditiously as possible to assist with either discounting or confirming the detections. echo is the closest to the site. ocean shield will be delayed while she pursues an acoustic noise in her current location. a word of caution. in the days, weeks and possibly months ahead there may be leads such as the one i'm reporting to you this morning on a regular basis. i would ask you, the media, to

treat them as unverified until such time as we can provide an unequivocal determination and i think that's very important and i ask for your assistance and cooperation. i assure you that we will follow up and exhaust every credible lead we receive. we need to keep at the forefront of their minds the families and friends of the 239 passengers who were on board the flight. speculation and unconfirmed reports can see put the loved ones of the passengers through terrible stress and i don't want to put them under any further emotional distress at this very difficult time. today also the international investigative team as of this morning advised of a correction

to the satellite data that has been used to calculate the probable flight path of mh-370. the correction arises from new information about the state of the satellite itself when it received transmissions from mh-370 during its flight. the effects of the correction is to raise the priority for searching the southern component of the existing search area ahead of the northern component. in other words, we see a higher probability of importance on the southern part of the search area. the whole of the existing search area remains the most likely area that the aircraft entered the water but based on the new advice the southern area now has a higher priority.

the air and surface searches for flight and wreckage today are already in progress and will be completed as planned in the available daylight. tomorrow's searches forging flight and wreckage will be adjusted to account for any new information. up to ten military aircraft, two civil aircraft and 13 ships will assist in today's search which will cover an area of 216,000 square kilometers. fortunately the weather in the search area is expected to remain good with a cloud base of about 2,500 feet and visibility greater than 10 kilometers. i'm now happy to take your questions. one at a time. >> have you got the data and analyzed it by the experts in australia. second -- >> sorry, sorry much just which

data? >> the signal. the data of the signal from the chinese ship and then analyzed it by the other experts? second, any condition is needed to be fulfilled before you draw the conclusion, i mean the confirmation. the third one is when you can draw the conclusion. >> well the process is one of, you know, verification. and essentially the information has been passed through the chinese authorities to the australian authorities with a request to do further investigation of the acoustic detection. so that is why hms echo and australian defense vessel ocean shield, which has special equipment, which will be useful in these circumstances, are

proceeding to the location of the chinese ship. now all the data that becomes available to the authorities is, obviously, looked at very closely. but at the moment, at the moment the data we have does not provide a means of verification. we have to -- we have to do further investigation on the site itself. and that is why all of these resources are being moved to that particular location. i think we have to let the experts take their necessary time to come up with the -- with their conclusions and on the basis of that we will, we will know whether it is credible contact or not. this is something you should

be -- you've all seen how we've handled the visual search over several weeks. when we first started the search there were many, many leads. some of them looked quite promising. we sent ships to pick up the stuff that had been identified on the search of the ocean and step by step we looked at it and then we couldn't find a connection of mh-370 and that one was discounted seen far none of the visual contacts that we've had and the wreckage, the material we have recovered from the ocean has been, i guess, linked to mh-370. we'll go through a similar process when we go under water. under water the environment is

quite difficult. there are lots of occasions when noises will be transmitted of long distances depending on the temperature layers and so on. there's a complexity of working under water that makes the task quite complex. we have the necessary expertise to be able to operate there, and obviously we will have the expertise on land supporting the efforts of the people who are doing the work at sea. >> based on your professional knowledge, if it is confirmed that a signal comes from the black box, how difficult would it be to get the black box in this area and if it is confirmed, would you announce the result immediately or wait for the confirmation wither to four countries. >> look, the water in which the

ship is working at the moment is very, very deep. i think it's in the order of four and a half thousand meters, four and a half kilometers straight down. so, you know, any recovery operation is going to be incredibly challenging. and very demanding and will take a long period of time. that's if there's anything down there. i mean, first of all, we got to establish the fact that there is something down there. we're a long way from making that conclusion. that's why we need hms echo, and the australian defense vessel ocean shield to come to the location because they have special equipment that can help us make the judgment whether there is anything down there.

but, i think the fact that we've had two detection, two events in that location provides some promise which requires a full investigation of the location. >> just to clarify just what you are talking about. then the two detections in the area, if the boat pick up something and second one in a separate area s is that correct, two kilometers s is that what you are saying? further, just expand on the ocean shield -- >> okay. the first detection was about i suppose 36 hours ago. not last night. the night before. okay? and i believe it was just a quick acoustic detection and

then nothing. the chinese ship stayed in the area, investigating the site at which this had occurred, and yesterday afternoon perth time, there was another acoustic detection and that was less than two kilometers from the original detection. now the fact that we have two detections that are slightly apart in terms of distance, but in an ocean that size, you know, two kilometers is not a large distance, and of course they are separated in time over a period of 24 hours. the second transmission was orb i should say acoustic convenient was for about 90 seconds.

so we obviously have to investigate it fully and we will do that and we will let you know at the completion of the process what the outcome is. i mean, we're not going to hide anything from any of you. >> if i can ask you, how long do you believe it will take for the hms echo and ocean shield to be to get in position and investigate this further and is this location within that southern sector that you've now defined as being a more credible lead as to when the flight went down? >> yes. in answer to your last question, yes, the area is in the high probability area, yes. the second thing is in terms of how long it will take the two ships to get there, hms echo is closer. she will get there, i would

think, fairly quickly. i'll take advice from come mow -- commodore lee vi. in terms of ocean shield, she is in the process of exploring another acoustic event which we need to look at to determine if there's anything in that. so this is a pain staking process, and if we get any lead whatsoever, we investigate it, and if it is significant, we continue to investigate it until such time as we say, well, no, that is not connected to mh-370. so it is something that takes time. we're dealing with very deep water. we're dealing with an environment where sometimes you can get false indications. there are lots of noises in the

ocean, and sometimes the acoustic equipment can rebound echo if you like, and all sorts of issues around that. peter, would you like to say anything more? >> just in term of the timing, i believe hms echo is approximately 14 hours from that position and as air chief just mentioned ocean shield it is itself investigating another acoustic detect she's made and once she's completed that activity, if it's decided to move her down and that proves to be not the beacon up there. it will be approximately 2 hours to recover her toed pinger equipment. so it will be over a day before ocean shield is there. >> we're talking a matter of days before both ships are positioned to be able to either verify or discount. >> that's correct. >> we're not talking hours.

we're talking days. >> we're talking days, correct. >> can you describe -- >> this is only happened within the last 90 minutes. we heard a report back from ocean shield from the towed ping operators on board there. they picked up a detection. it is very early dates and the note of caution that air chief marshall mentioned before, i would reiterate. we are still investigating that. we are not yet sure whether she will be tasked to remain there. if it's promising she will to investigate that particular detection, if it's not, then i expect she will be retasked down toward the chses ship's position. i would imagine it would take most of today to actually resolve that location where ocean shield's position is. as you can appreciate, she has 600,000 of tow behind her, to turn around and go back over a area of water again, it takes quite some time for a ship to

physically to reverse course. i will not expect a decision at the earliest. >> obviously, this is a really promising -- couple of detekses we've had. >> absolutely. this is -- of the search and the advertised time for the life of the batteries in the beacon are 30 days. now, sometimes they last for several days beyond that. say 8 to 10 days beyond that, but we're running out of time in terms of the battery life on the emergency locater beacon. you are right. >> the detection that you

mentioned that was the most recent, does that mean it's not being treated as seriously as the chinese detections? >> no, not at all. i mean, we have two -- well, we have three separate acoustic events. two with the chinese ship and we have another one with ocean shield. we're treating each of them very seriously. we need to ensure, before we leave any of those areas of detection, that there is no connection to mh-370. so we will work in those locations until we can say, yes or no. so we treat every -- we treat every lead that has any sort of promise very seriously and we don't leave it until we've exhausted all avenues of investigation. >> so will more resources going

to go that southern site then where ocean shield is? >> well, ocean shield is probably the best ship out of there to investigate this sort of acoustic occurrence. she obviously has the towed pinger which has been described to you by the commodore but she also has a remotely operated vehicle which is highly capable and we will see where it goes, and i'm sure as the commodore said, we're going to be looking at several hours, maybe a couple of days before that one might be resolved, but as soon as that -- say if that one completes without verification, it will then be tasked to go down to the chinese ship's position, and if in the meantime other leads come up, we will prosecute all of

them. we will, you know, we will pursue these leads to their conclusion. >> how far apart are they? >> well, it's 24 hours. they are a long way apart actually. 300 nautical miles. >> you cannot be sure about the frequency to the ocean shield? >> this was late breaking news. i thought it was important we're totally transparent with you. i want you to know the search is a dynamic thing. things are happening all the time and this broke this morning. this broke, what an hour ago? and i thought it was very important that you be informed about it because we are -- it's like the visual search, we are dealing with identification of whether an acoustic event has

anything to do with the downing of the aircraft. does it represent that the aircraft went into the sea at this location or not? and it's the same with the way we prosecute the visual search. the visual searching is ongoing. ships are going to have a look at the white objects that were found in the sea yesterday, and they will be looked at closely, and, again, was this object, could that have been aboard mh-370 or is it something else? and we've done that continuously over the last 30 days with all the visual objects that have been recovered from the scene. can i just -- >> i just wanted to know.
