they were made of pvc pipe. they contain timers to set off the detonators. it included powder from fireworks and they include shrapnel. what do you make from this combination? >> i looked at these real closely. looked at the x-rays. have handled many like it. i think in a totality of the circumstances, i think clint makes a great point, maybe they were not intended to detonate. that's a point you would consider. my analysis would be they were intended to detonate. just from what i see. here's some of the reasons. you don't put shrapnel, hidden shrapnel, glass, inside a pipe, to scare anybody. it's not going to scare anybody. you're not going to see it. if you want to put shrapnel to intimidate or, like, in a hoax device, you tape a bunch of nails around the outside of the bomb so the visual attack of your hoax bomb you see. that's not here. this is hidden shrapnel in the bomb. that makes me think this bomber wanted it to detonate. look at it defusing in the firing system, i can see some flaws i won't talk about. we would never want to arm the bomber with goo

this is volatile material contained very tightly within these pvc pipes. and he said it exactly right. spoken like a true bomb technician. heat, shock, friction. that's all it takes. you could take that containment and just shake it very quickly, and just that would be enough friction to ignite that material within that pipe and that alone would create an explosion and create shrapnel that could easily kill somebody. >> and pamela, you were there at the justice department for that briefing of the fbi director and the attorney general and others. walk us through the background, how significant this development is. >> well, i think, also, just to set the stage here. the press conference happened just hours after the president sent out this tweet about the, quote, bomb stuff overshadowing the momentum he had. and then you go to this press conference with the director of the fbi saying, this was not a hoax device. this was serious. the criminal complaint says that the intent was to use it to kill, injure and intimidate individuals. this was serious, which is w

pvc pipe. there's two types of casing for this. one is pvc pipe, stuffed with nails or nuts or bolts or use a cast iron pipe. the package becomes a shrapnel. four components. a power supply, typically a battery, initiator, typically a blasting cap, the shrapnel, the things stuffed inside of it and fourth would be the switch. was it electrical fuse, a trip wire or was it possibly a key fob or cell phone somebody was going to activate once the package had been delivered. >> it's been said these are crude devices. just because they're crude doesn't mean they're any less potent. >> i was in afghanistan. i saw what it looked like whether he an ied went off. limbs get ripped off of people. pipe bomb that many size could have done massive destruction. anybody in that room could have been killed or maimed and a lot of destruction of property. >> you talked about the number of cameras. there are cameras all over, the one delivered to cnn was delivered by courier. the one to soros was left in the mailbox. i'm sure there are more cameras here

the device was very crude, pvc pipe, red and black wire. very hollywood.icators like what would be in a hollywood movie and the digital timer that's present there. none of that would be, you know, what a real bomber would want to do. if it was a real bomber, laura, it would be somebody that is going to send the device through the mail that would be victim actual waited when it gets there. a timer is not a means of deployme deployment. >> laura: danny chris cuomo said something differently about what he considered to be -- excuse me governor cuomo, about this device. >> it is wrong to say, in my opinion, that these two or three fake bombs. there is a question as to whether or not the bombs were designed to detonate or to intimidate. >> do they have a -- >> the question is the motivation. >> laura: danny? >> that's laughable. laura, i commanded the oklahoma bombing investigation. i've been to bomb school. i've been the victim of an ied. i know how these things work. either this guy is the alfred e newman of bomb makers or he had no intention of these things

we're told the devices were all made of pvc plastic, one-inch diameter plastic pipe with end caps like this. inside was apparently explosive powder and little glass shards to act as shrapnel. this is an investigate lead to try to figure out where it came from because many times it will have a bar code on it and that will help them find out perhaps where it was sold. so there's lots of investigative detail here to be looked at and the optimism is pretty high they'll be able to find a suspect soon. >> garrett what can you tell us about the two devices that were sent to the former vice president? >> well, as pete was just laying out, they bear all these same hallmarks of the devices we've seen delivered across the northeast in the last few days. the envelope, the manila padded envelop with the address to joseph biden with his full name and his full address here in delaware. we're not showing that address for obvious reasons. but a very scary scene for folks in this area this morning when they woke up with bomb disposal vehicles here at this postal sorting facility. essentially a place whe

and "x-rays though there was likely shrapnel inside the pvc pipe as well." because of the list of targets who they were sent to, and there's also late-breaking reports about a device maybe having been sent to congresswoman maxine waters tonight, again, that's late breaking news. we don't have the same information about that device that we do with these other five where we have law enforcement sources speaking to nbc about the character of those devices. but because of the list of targets, which includes these people, including also congresswoman maxine waters, there's been lots of inference and speculation today, unavoid my, over the intent and motivation of the bomber. the person who is sending out these devices. obviously, all of these people and institutions have been targets for invective and condemnation by the president and his supporters and conservative media. george soros personally even today stars in an official new republican party ad as an evil, shady financier who the national republican party is trying to associate with democratic congressiona

. >>> each device consisted of roughly six inches of pvc pipe, a small clock, a battery, some wiring, and what is known as energetic material. these are not hoax devices. >> that is fbi director christopher wray talking more about those components that were inside those package bombs, thankfully none of which detonated. now, those packages are giving investigators crucial clues as they work to really figure out more about the suspect and about his motives. joining me now is nbc justice correspondent pete williams. pete, let's just start right there. were those devices actually created to explode in were they intended to go off? >> that seems to be what the fbi is saying when the fbi director says they were not hoax devices. they clearly didn't, thankfully, work, but at this point the supposition of investigators is that's not intentional. the bombmaker fortunately didn't do it right. but they believe based on the construction of the devices, the fact that they were wired up in a way that should have worked but didn't work, they believe they were not hoax devices. >> is this all, pete,

and as well as information from the actual possibility of the pvc pipe providing information.or of the package, there's always, of course, the potential for physical evidence like dna, fingerprints, et cetera, et cetera. >> jimmy, what does it say that none of the bombs have exploded? >> well, it may say we're doing a really good job of screening because after the anthrax letters a number of years ago, we have put in place a number of cauti cautionary locks where these packages don't necessarily go directly where they were mailed, especially if they're to government officials. on the other hand, we don't know much about the initiating system. it's rather strange that we have a digital clock. if anything went through the mail, how could you possibly know how could it possibly be a timed event. usually, package bombs and sam may want to speak to this, but they're often operated in this case. and then of course, you have your small diameter to look at and say only a few materials could do anything, could actually detonate. i have done 130 pipe bombs in a research program, looking

>> in some of the pipe bombs and ieds i saw in afghanistan, the pvc pipe, there are going to be shards off that, that's not like nails or if they used a cast iron pipe, with threaded end pieces they screwed together, where the packaging backs a fragmentation. three things from the bomb that can kill you, overpressure, soft tissue damage. fragmentation. if it's a pvc pipe, they're packed with nails and nuts and bolts, and third, what happens when the bomb explodes, it causes a fire that burns a person that's handling it or causes a fire and people die from asphyxiation. >> we have the kbom, and then we have the man or the men and women who did it? where are we in terms of the man hunt? >> that's the first question, the fbi, the secret service, postal service and others are going to form a task force and they're going to start hunting down the individual or individuals or group that caused this that sent these bombs. part of that is going to be looking at the forensics of the different devices. the envelopes. the stamps, whether they licked the stamps, whether there are forensics. like d

are made, and what appears to be shrapnel that we are told in this device is glass and made of the pvc pipe and all of these are characteristics that they could use to use that forensic investigation, but then the other side is the ones who were sent through the mail, and now we don't know exactly how many were sent through the mail, and most if not all of them, and cnn says that the one it got was delivered by a courier, and that is itself a piece of potential lead to try to find that courier, and how did that package get into the kourcan i -- courier's hands and all of that. and then, the mack packages where where were they mailed, what time, and what postal facility handled them. and so a lot of optimism, but so far, no suspect we are told. >> and ron, back to this morning we woke up up and i turned on the tv and local channel 4 nbc already showing us that major police presence downtown. give us the rundown of what happened. >> yeah, chris, it is frightening to wake up to that kind of the news, and that happened around 5:00 or 6:00 a.m. this morning again, and as you know, try beckk

they are six inches long made out of pvc pipe and they all have a literal battery -- little battery that is similar to what you would find in a watch. they all had shards of glass in them and at this point none of them have gone off and nobody has been hurt. police are very much trying to figure out who is behind this because they simply do not know if there are more packages out there. they are telling people to remain vigilant. if you see something suspicious or receive a package, or something that looks like it, don't touch it and contacted doherty's. until they are able to find out where they are coming from and who they are coming from, they don't know if there are more out there. they are looking for help and if you know something, contact the parties. >> there is concern there could be more packages in the mail. thank you for that. >>> the investigation is having an impact in the bay area where politicians are speaking out and bart is stepping up patrols . >> henry, why are officers increasing their presence on the system? >> reporter: police tell me the added patrols are an extra

if it's a pvc pipe, they're packed with nails and nuts and bolts, and third, what happens when the bomb explodes, it causes a fire that burns a person that's handling it or causes a fire and people die from asphyxiation. >> we have the kbom, and then we have the man or the men and women who did it? >> that's the first question, the fbi, the secret service, postal service and others are going to form a task force and they're going to start hunting down the individual or individuals or group that caused this that sent these bombs. part of that is going to be looking at the forensics of the different devices. the stamps, whether they licked the stamps, whether there are foreearnsics they can pull off the envelopes. my point is, there's a huge digital and physical forensic trail that is left any time you do something like this. and the authorities, the fbi especially is good at huntsing that all down. >> and the reason it matters is, they don't know yet whether these devices were functional or made to just look really good, and if it's the former, you mele need to get this guy. it's so impo

but he was fairly specific, the fbi director saying as far as these devices go, six inches of pvc pipe, a small clock, battery, wiring, potentially explosive materials. the fbi director making it clear that these were not hoax devices, though they aren't entirely sure at this point whether they were functional or not. the fbi director saying at this point they are pretty confident that they have found the right person, but when he was asked whether or not there might be more of these devices out there, he would not say if that was the case, just to say at this point it is very much an active and ongoing investigation. you are looking there at the attorney general, jeff sessions, who made this point very clear. if anyone tries to do anything like this again in the future, law enforcement will come down on them. >> let this be a lesson to anyone, regardless of their political beliefs, that we will bring the full force of law against anyone who attempts to use threats, intimidation and outright violence to further an agenda. we will find you, we will prosecute you to the fullest extent of

i think what chris is saying there was some kind of explosive material in these pvc pipes, and that qualifies technically as a pipe bomb or weapon of mass destruction. and under certain conditions those things could have detonated with certain temperatures, certain type of pressure or jostling, for example. but they weren't really functioning bombs in the sense of having a detonator. trish: interesting, but then it leads you to the suspect that he was not smart enough or experienced enough with these bombs and explosive devices to fire them off, or waits that he was just trying to scare people? ways your sense of that? >> this surely is speculation. i don't have inside information. i think he was trying to cause the reaction that he did in fact get, a media frenzy and a lot of publicity for himself and whatever his cause is. obviously he's demented. you won't hear the investigators say he's crazy because they don't want to late ground work for earn insanity defense. but by definition this person is disturbed. trish: i spoke to a source who attend two years of high school with this suspect, an

we have a 1-inch pvc pipe with caps on the end and -- >> that's what came in the mail. >> right. the explosive stuff goes inside. >> small. >> might have been shrapnel. wires and a mechanism to set it off. what we don't know yet, maybe you know, we know some of them were faulty. we know some of them might not have gone and the ingredients necessary in most cases to go off. were the things sent in the mail bombs? potential bombs? were they hoaxes? do we know that yet? >> i'm glad you asked this question. so what we know is some of the devices were incapable of going off. were they incapable because they were not built correctly or incapable of going off because they were never designed to actually complete the entire detonation chain? and we could spend the next 40 minutes just explaining that. >> right. >> but to just bottom line it, we need to wait to see what the results of this investigation are. it may become clear in the court document that is danny was referring to earlier and whether or not the motive here was for them to go off or whether or not the motive was to just inc

all those component parts like pvc. i'm sure fbi agents are out talking to all the large hardware stores in those communities wherever they find those packages were mailed to for anyone who might have bought an unusually large volume of pvc pipe. i think resolving the case quickly is the best way to calm the public. >> tough to do when more packages keep coming in. i want to go back to rehema ellis. it was just a few minutes ago you walked us through it. we saw that police truck that looks somewhat like a cement mixer carrying that suspicious package. make its way out of the street and soon to be out of new york city. so now that that is gone, what's happening there? has the street -- is the street closed down? can pedestrians walk on it? >> no, not at all. there's no pedestrian traffic going down this street, stephanie. about 50 yards from where i'm standing, it is that mail facility, mail sorting facility, and you can see the flashing lights on an nypd police vehicle right now. it's pretty much right across from the e

there was a pvc pipe used to contain a potential explosive. he's being careful here not detailing the exact explosive. that it had a small clock and it had a battery. and we know there were certain things, and i'm not going to describe all of them here because i don't want to tell people how to build a functional bomb. but there were certain things that made these bombs capable of operating. and he was very clear, and i'm going to quote the director here when he said these are not hoax devices. so in other words in his estimation, they were not intended to be a fake or get everyone fired up about a potential explosive device. he's not calling them a hoax device. he's calling them an actual device. so the fingerprint that we found was on a package that was sent to congresswoman waters, and in addition to that going through my notes here from the press conference he did highlight there may be other packages in transit we have to keep an eye out for. >> we know 13 at the moment. >> 13 at the moment. the fbi director said there may be additional p

so you have pvc pipe. he said it was filled with a low explosive. he said it had a battery and it had a digital clock. so if this person wasn't capable of putting all that together, well, then that's on that person. but there's no doubt about it that if things had gone differently here, the potential did exist for these bombs to go off. >> paul, let me give you the last word. what is the climate like for law enforcement as they now have to go try to root out and prevent any sort of copycat conduct from anyone else so inspired by the tone and tenor of the political discourse? >> yeah, you know, law enforcement in some ways, i think, feels it's working at odds with the commander in chief, with the nation's chief executive officer, who supports it when they're going after young, black, and latino men, but when they're going after him or investigating even national security, he doesn't seem to have the same concern. and, nicolle, how high the stakes are, are revealed by what's going on right now, which is that the fbi is treating this like a terrorist c

there are suggestions that they were made up of a pvc tube, that there was a pyrotechnic powder not theilar to what would be used in a firework, connected to a digital clock, as well as some shrapnel. and that shrapnel was clearly intended to cause harm should they explode. and very briefly, any idea of motives at this stage, or too early to say? it is clear that if you take a look at it, at this stage what the authorities are looking at is that they were all sent to individuals who have criticised donald trump, individuals who are connected to the democratic party. it would give you a sense at the moment that that is what they are looking at. however, it is too early, they are making that point, and fundamentally at the moment, it is still an active investigation. also making news today, the un humanitarian chief has warned that half of yemen's population, a total 01:14 million people, is at imminent risk of famine. the un says the task faced by aid agencies was bigger than anything they'd seen in their working lives. the head of a united nations investigation in myanmar says rohingya

brian: have ones pipes and pvc. used to be able to pick up the metal.ow they pick up the pvc, obviously plastic. makes it additionally centralling. whatnot clear to me is -- and might be to use of you guys. is black powder or blasting cap in any of them or is this just a makeup of a device? because i know in the cnn one reported by the "new york post" today, they said there was no blasting cap in that. i'm wondering whether any other ones that potentially could have detonated? you do you know, dan? >> that's the key question. obviously, brian, the key component of an explosive device is an explosive. if you don't have black powder, you don't have an explosive. the use of pvc, you know, again, speaks to just such an amateurish approach, this has to be intentionally amateurish. it doesn't make any sense. ainsley: dan, how long do you think it will take before they are able to determine who sent these. rick hawaiian said it will hahnr less. >> i say less. i wouldn't be surprised if a target was located today or tomorrow. again, they are having these -- mul
