heavy security dominating this fourth of july holiday. law enforcement out in force with calls for vigilance on this 239th birthday of the nation. plus -- out of control fireworks. several people hurt when malfunctioning fireworks fly into the crowd at a colorado town display. and can you imagine this, this huge catch, this fisherman looking for grouper but ended up with a shark in hit kayak. >> i don't think he found so

funny. >> good morning, i'm alison kosik in for christi paul. >> i'm victor blackwell. good to start a saturday with you. as millions of americans, i'm shore you're one. celebrate the fourth of july holiday, officials are warning you to be vigilant. >> law enforcement on alert ramping up security from national monuments to state parks as officials warn celebrations could be the target for terror attacks. >> the concern is felt overseas as well as embassies, consulates, meet with security teams and review their efforts to stay safe. one u.s. air force base in england is calling off its celebrations today because an increased -- because of this increased security threat. >> so far, there haven't been any specific threats but intelligence officials say there has been an increase in chatter in the days leading up to the anniversary of our nation's founding. >> sunlen serfaty joins us with a look at security at site of one of the country's biggest celebrations, the national mall in washington. good morning.

>> reporter: good morning, victor and allison. hundreds of thousands will gather on the national mall later today. while a major security presence isn't anything new for washington during the fourth of july, this increase in strong warning coming from then te n intelligence community has officials on jeej edge. >> reporter: checkpoints for those watching fireworks with 18,000 feet offensing in place to protect the national mall. special patrols at washington landmarks and heavy police presence in both seen and unseen ways. >> we prepare for worst-case scenarios and we have contingencies in place should they occur. we don't anticipate that they will. >> reporter: plup of the anxiety stems from a bulletin issued by the fbi and homeland security, warning of potential attacks by isis this holiday weekend. u.s. officials say there's no

intelligence about specific or credible plots but there has been an uptick of chatter from isis, encouraging followers to attack. the dominant concern, homegrown violent extremists, supporters of isis within the u.s. who may be inspired to carry out their call to action. >> in the year of social media and phenomenon like isil, unlike al qaeda in the old days there doesn't have to be, won't necessarily be a commanding and control relationship between somebody who instigates an incident and isil as an organization. there are self-radicalized, self-organized people on social media. >> reporter: so-called lone wolf attacks are a challenge for the intelligence community, much harder to pick up ahead of time. it's not just in washington. police forces across the nation including new york, philadelphia, and los angeles, are on high alert, and not just in the streets but online. >> there are people assigned

monitoring, monitoring social media and known websites. >> reporter: looking for any specific -- >> that's correct, any kind of watch words. so it's constantly being monitored. >> reporter: threats won't go away, likely with the holiday. law enforcement officials say another area of concern of a possible threat is because this is also the holy month of ramadan which lasts until the 17th of this month. so likely this sort of anxiety, sort of increased security posture will not go away until then. >> and from washington, we head to new york where boris sanchez joins us live from pen station. good morning. governor cuomo calling new york a top target for threats. what extra security are you seein seeing? >> reporter: very expanded law enforcement presence here. about 42 million people traveling this weekend, so officials are focusing in on travel hubs like penn station in new york. you mentioned governor cuomo,

yesterday announced expanding staff and patrol at emergency operation center in the city. officials have told us placing snipers and spotters in key locations and strategic locations across the city to watch crowds. also scanning for explosives by land, sea and air. 7,000 cameras across the city fanned out looking for any suspicious activity among crowds. officials telling us they're prepared for any kind of attack. >> when you look at that diversity of techniques you also see that they are following the isis call and the isis call, as well as that of other terrorist groups, has been to use what you have on hand, and that means if you can make a bomb, you're a bomber, but if you can't, use a gun. if you can't find a gun, use a knife. if you can't use a knife, find a car. that's a broad spectrum of

threats and it's something to prepare for. >> reporter: the governor also asking new yorkers to stay vigilant, report any activity that seems out of place. clearly this is a very busy weekend for law enforcement. >> those fireworks displays happening tonight, boris, across new york city. what kind of presence should people expect as they get out there to watch those shows? >> reporter: certainly. like i said before, an expanded law enforcement presence. one unique note, placing special attention on the harbor and the areas out at sea where they have boats scanning for radioactive devices and explosives. clearly a full-court press this weekend. >> boris sanchez, thanks. let's bring in cnn law enforcement analyst and former fbi assistant director, tom fuentes. i want to start with you, to put

punctuation on what we heard from that new york city counterterror official, the call from isis to use what you have, where you are, fundamentally changes the view from the u.s. on these terror attacks. gone are the days possibly of large-scale attacks. >> very much so, victor. it not the al qaeda mass casualty plot, people going abroad for terrorist training, coming back to carry out an attack, say targeting transportation system. today's type of terrorism that isis purports, sporadic, spontaneous, not sophisticated but still the visualization of terrorism is something that they promote. whenever they issue a message. unfortunately followers tend to react. a couple of weeks ago they shoot a message to followers to make ramadan the most bloodiest on record. attacks in kuwait, tunisia, france. there's a worry whenever they issue a threat, people will try

act independently. >> tom, that makes it really difficult to investigate because often attacks are not orchestrated by isis but instead inspired by isis. doesn't that eliminate some of the quote/unquote chat that investigators typically use? >> that's right. in the old days with al qaeda, chatter was because the attacks were micromanaged by bin laden or ksm close to bin laden and that involved a lot of back and forth communication. okay, attack on this date, do those, do that, send us money, okay, sending you money, go to this bank, withdraw the money. you could track finance and communications, if not the specific content of communications you did see the amount of chatter going back and forth. now there's no chatter that way. they put out this, as mentioned, the word, go kill, and there's no need to respond to that. just go do it when you want to, how you want to, whatever's available to you.

when there's no back and forth traffic, there's nothing toint september. now, fortunately, most of these terrorists have put something on social media to indicate a desire to do something and somehow you know that word gets to the authorities, the fbi can then assign jttfs to look at that group or group of persons. but now, without that back and forth, you're left with the fbi trying to read minds. who is thinking of doing something? when are they going to do it? >> help us understand, we talked about it here a bit this morning, the calendar, not only the fourth of july but the holy month of ramadan and the increased value for some on attacking during the month. >> well, ramadan as you mentioned the holiest month for muslims, a period where they have to fast regularly. it's deemed to be the most holiest period for their lives. it's a very warped period for terrorists because they deem

themselves to attain greater spirituality if they carry out attacks during this period. we have it on record in the past, where ramadan attacks before. isis also believes in targeting symbolic events, fourth of july, of course, very important for all americans. they want to try to capture the attention to get the focus off from celebrations and more on the fear factor. but, at the same time, we should have a lot of faith and confidence in the u.s., local, and national law enforcement agencies. they will do whatever they can. after -- for the terrorist, they have to be lucky once, the authorities have to be lucky all the time. >> that is always the concern. thank you for joining us. tom, stick around, we'll continue the conversation throughout the day. a shocking sign inside a police van, telling cuffed passengers to enjoy the ride. it could be up right now in a city that has a real struggle

lot to police since his capture. detailing how law enforcement came so close to getting him before caught. also finding out more about his fellow escapee, richard matt, who was shot and killed by police. matt reached out to his daughter in a letter. cnn national correspondent deborah feyerick has details. >> reporter: killer richard matt was so confident he would elude immediate capture after breaking out of his maximum security prison he sent his daughter a letter. law enforcement sources telling the buffalo news, matt wrote, i always promised i would see you on outside. i'm a man of my word. the daughter, who lives in a zbush of buffalo, new york, reportedly receives the letter three days after her father's escape from clinton correctional facility 350 miles across state. there's no indication she knew in advance of her father's plans. matt spent 20 days on the run, before a border patrol special operations team found him alone behind a tree. he was shot three times in the

head after aiming a .20 gauge shotgun at an officer. matt's body taken to the buffalo area after his family had a change of heart and decided to claim the body. the funeral home said no public or private services. sweat listed in fair condition. he continues to heal from two gunshot wounds sustained during his capture. police put out a photo of the type of backpack he was carrying before arrested two miles from the canadian border. they are asking the owner to come forward. possibly to trace the escapees' route. the department of krex correcti has been criticized a week before the escape. the corrections official tells cnn only a partial lockdown was necessary because the melee lasted less than a minute, involved no weapons, and only one injury. security measures have been tightened to ensure daily random

welcome back. here's a look at other stories we're watching now. >> 20 minutes after the hour. massachusetts police are asking for help in identifying a toddler whose body washed ashore along the boston harbor last week. officials have released this computer generated sketch of the girl. they say she was about 4 years old, you see here brown hair, brown eyes. they add that her body, found in a zipper striped blanket inside of a trash can, showed no obvious signs of trauma. so far, they've received thousands of tips but still have not been able to identify this girl. let's take you to texas now where a man has died in a gator attack. the man took off his shoes and shirt after someone warned him not to swim in the water. a nearby sign said "no swimming, alligators." however, the man jumped in anyway and was immediately attacked. a state game warden on the job

for 22 years says, it is the first fatal alligator attack he can recall probably because people didn't jump in because the sign said "no swimming, alligators." a fireworks malfunction injuring nine people during a show last night in colorado. a shell exploded in its tube and landed in the crowd instead of firing into the sky. look at this. >> oh! whoa! >> what's going on? >> low-lying one. >> fireworks. >> whoa! >> oh my god. >> holy [ bleep ]! >> that's scary. all nine people treat for minor abrasion burns at the show and then released. an investigation was launched immediately after the incident. >> protests in greece now where polls ahead of vote on referendum for a proposed new bailout, the polls are too close to call. those in favor which would require greece to accept more

alwa austerity are leading those who propose it. it could mean the beginning of the greece exit from the eurozone. a live report. cnn's richard quest is there in greece. he'll join us later this morning. back here at home, flood watches, severe storms, all of that's going to impact many july 4th celebrations, bummer. >> ivan cabrera, this is no the a great weekend for some people. >> it's summer, this happens every summer. some areas get thunderstorms through the afternoon. but the problem is, this year we'll have a line that is not going away. the potential for flooding is here i'm doesn't think we'll talk about severe storms. there will be a few isolated storms that could reach severe levels here. one now across northern mississippi mainly flood threat here. talking additional 1 to 3 inches in an area that has picked up 6 inches in the last 24 to 48 hours. this is what we're talking about. look at flood watches from arkansas through mississippi,

alabama, tennessee, and into parts of georgia, including atlanta as well. a soggy fourth of july. this is not the kind of day you wake up, clear sky and then afternoon storms. no, it's already raining and it will continue to rain throughout the day as we put the forecast into motion. right along that boundary, not much movement here, that is why the flood threat is there. it's going to rain over the same areas and we have showers across the northeast. i think we'll be in good shape up there as the showers begin to push off east after 9:00 p.m. and that's when the fireworks get going here. in the southeast, looking for more heavy rainfall. as far as accumulation, anywhere from 1 to 3 inches, that's going to be a problem here. stay indoors, have fun, enjoy yourself. keep in mind heavy rain across the southern u.s. on this fourth. >> watch the fireworks on tv. >> that's good. that's good. >> not? >> cities across the country stepping up security july 4th. how do authorities and the military prevent lone wolf attackers from setting their

sights on holiday events? more on this threat, next into later this morning, there are these lingering tensions after the death of freddie gray in baltimore. well, a photo has emerged from the inside of a police van in baltimore that one sergeant calls concerning. now there's an investigation. what are the larger implications here? hosting the game for seven years. >> five-minute walk to the all england club. you can see the courts and hear the roar from center and number one courts. >> reporter: apartments with sw-19 post code start at 2,200 a week and family homes top out at 23,000,000. players willing to play big for the convenience of walking to work. >> so just something really nice

>> bottom of the hour. thanks for joining us this saturday. happy july 4th. on this weekend, security across the nation is ramping up. new york's governor adding manpower, enhancing monitoring operations for the holiday. officials across the country are boosting security at fireworks shows and landmarks. concerns are much higher this year, in part because of the calendar, fourth of july happening during the holy month of ramadan and terrorist networks taken to social media, urging supporters to carry out attacks during this weekend. among the fears this holiday, threat of a lone wolf attack on soft targets. those places more vulnerable to attack. officials worry that there could be attacks similar to the recent ones in tunisia and france. cnn's rene marsh takes a closer look at what's being done to protect july 4th festivities.

rene? >> reporter: in the nation's capital alone, 600,000 people expected to take subways while 2 million flyers per day are also traveling to fourth of july celebrations. but as americans move from point a to point b, law enforcement remains on high alert for terrorists on u.s. soil. >> we prepare for worst-case scenarios and we have contingencies if place, should they occur. >> reporter: those reassurances echoed ahead of celebrations across the country. >> philadelphia is already part of an enhanced security network. >> reporter: despite the assurances there's only so much authorities can do to secure so-called soft targets. >> what i fear the most is what we saw in tunisia last weekend, which is one or two people with automatic weapons and they simply go into a place where it's really crowded or they go to a bridge where traffic is

stopped or a tunnel and just simply taking out 4050 people. that would be as effective as any large-scale bomb. >> reporter: and isis has been encouraging followers to launch attacks wherever they can. >> look behind me, it's the most iconic image of america. so we know that it is somethng that people who don't like us would want to do something and maybe try to make a statement. >> these kind of targets are soft targets. they're very easy to go after. you've got a gun, willing to die for your beliefs. >> reporter: authorities say the best thing anyone can do is be aware of their surroundings. if they see something that doesn't look right, alert authorities immediately. airports have been seeing high volume as well. tsa officers are being extra vigilant, flyers should expect random checks at the airport. and if you take a look, just behind me, you see that setup, that is where the fourth of july concert will happen the nation.

capitol. law enforcement, they will have their eyes closely glued to this event. they're expecting thousands and thousands of people to show up an important point we want to make sheer, they are warning people to abletter but not telling people to stay home. they want people to come out and enjoy but observe the surroundings around them. victor, alison? >> rene marsh, thank you. let's bring in cnn military analyst, retired general mark hertling. >> we've talked about the law enforcement role, the police departments and so forth. but i wonder, is there a military role this weekend that likely we're not seeing in protecting some of these sites? >> certainly not yet. this is all related to something called -- federal forces, u.s. military cannot get involved in these kind of security actions with the police. now, you could -- a governor

could call. the national guard if was an extreme emergency and that's hasn't happened yet and it's difficult to defend against soft targets. we have air force flying cap all over the united states, that's always happening, combat air patrols in case of some incoming aircraft or something they and they react that way. soft targets are hard to defend against. >> that's a term we talked about after 9/11, on that day. let me ask you about not just the law enforcement role of military but the target element. i mean, being out in public this weekend, wearing the uniform, i mean, is there a direction that's coming from higher-ups. >> well, there always is. it's usually commanders will usually tell their forces, do not wear uniform in public unless there is some type of special occasion. now, certainly there are a lot of parades on the fourth of july and certainly a lot of cities

that are close to military bases like to have soldiers participating or things like rotc units participating. again, that's conducted under an assessment and what are the dangers there, should we allow military forces to do those kind of things. all of those are handled by base commanders, post commanders in the local area. >> so, you brought up assessment and there was a directive that came out for military bases across the world and including the consulates and embassies, to look at their security procedures what happen does that likely look like in what is that? >> that happens quite a bit, actually, victor. as a commander in europe, as an example i commanded in europe two years, you would get requests from the department of defense, the embassies have received it from the state department, saying, conduct an in-depth threat assessment because of these things. now, what i'll tell you, as

commander in europe, every event we held we would conduct threat assessments on the event and we had continuous, ongoing threat assessments. you have a small group of people that come together, that actually do that. but i think the notion that this weekend, because of the fourth of july holiday, and because of the admonitions of one of the isis leaders saying, attack during ramadan, this will give you additional credit in heaven during this holy month, that assessment has been ordered just to make sure everyone's doing it and turning it in. it's a written document that you conduct intelligence feeds and see how you are prepared to address any threats in your local area. >> general mark hertling, thanks so much. >> thank you. police in baltimore have opened an investigation after a sign found inside a police van that tells passengers to enjoy the ride. how did it get there? will it increase already-heightened tensions in

photographer. the image going public as tensions remain high following the death in police custody of freddie gray. you remember this story. while the department could not confirm the authenticity of the sign to cnn, officials say they are taking the issue, quote, very seriously. although i think there is some confirmation from the department that it's authenticated i want to bring in cedric alexander, public safety director for de kalb count any in georgia. good to have you with us this morning. >> good morning. >> first thing that jumped out to me that is there is a sign inside a police van. are there snarky signs inside police vans often? >> i've been in law enforcement a long time and i never seen a statement as such in place inside any prisoner van. so, i'm quite sure to the community there this is a very aggravating event, and certainly to the police department as well, too. and i'm very acquainted with the

commissioner there, tony patch. he certainly has real concern with this and has launched an investigation into this signage that you see there on the inside door of this van. >> of course, the inference here, it refers to these rough rides that we've reported on. does it matter to you, we know this was just discovered this week, but does it matter to you if it was placed there pre-freddie gray or post-freddie gray? >> it's disturbing either way. >> yeah. >> if it was there before freddie gray, and it's suggestive of this is an attitude that permeates throughout the culture of that agency if it was placed after freddie gray, then someone, somehow finds this to be humorous and it's not. it not a good light you're trying to shine on your department particularly in a community where the leadership and community leaders are trying to establish a much stabler, stronger relationship.

so there's some work there still yet to be done in that community but i'm more than confident that that work is going to take place, both with its leaders and police and the community as well, too. but that signage certainly needs to be investigated, will be investigated there in baltimore and i think at the end we'll see what the outcome's going to be. >> in addition to the baltimore investigation, there's a doj investigation looking into the baltimore p.d. to determine, and i want to read here the quote, if there's a pattern or practice of violating constitutional righ rights. how do you imagine something like this playing into that larger investigation? >> what it suggests here, victor, something systemically and culturally may be wrong inside that police department. if that signage is an indication of how it takes care of its prisoners that we've become responsible for once we take custody of them, that's a much bigger issue. he here again, i think an investigation will reveal

specifically as to when that took place and person or persons involved. >> cedric alexander, good to have your insight. >> happy fourth. >> you too. this is dramatic video. 10-month-old baby drifting out to sea almost a mile, crazy. this, as the parents sunbathe. you can see her in her yellow inflatable. rescuers frantically try to reach her. more details next hour. whoa, a terrifying moment as a fisherman swims for his life after the kayak he's in flipped over or is flipped over by a shark, that's next. we live in a pick and choose world.

man, listen, that would be last time you would see me out that far in a kayak fishing. you see the guy here swimming for his life after that shark flipped him off that kayak. this is in the middle of the ocean. ben, fishing for a goliath grouper, when this eight-plus foot bull shark knocked him into the water off the coast of florida. you see the captain, he swam to safety on a support boat. but then, here's the part i don't get, he went back into the kayak to finish what he started and unhooked that fish. he spoke to cnn last night about this adventure.

>> i made it to safety and we flipped the kayak back over. i felt like the shark had won the battle. i thought i was winning but when he flipped me over i fell like i lost battle and it was kind of vin d vindication. like if you fall off a horse, better get back on. >> okay. chancy didn't let the near-death experience shake him. back in the water again yesterday. >> you wouldn't go back in the water? >> i wouldn't go back into that water. >> all right. >> a shark right there. we know what's happening right now with sharks. >> all right. this shark attack coming at a time when east coast is already on a heightened alert. you know there have been ten attack as long north and south carolina along the coastline. that's higher than the average of six attacks per year off the coast of those two states. and the latest attack happened near ocracoke island in the outer banks. a man swimming in waist-deep water when a shark pulled him

under water and bit into his rib cage, hip, lower leg, both hands and managed to get away leaving a trail of blood. surprisingly, he's in good spirits, recovering in the hospital. now some people are second-guessing their weekend holiday plans, though. others are still planning to hit the waves. i want to talk more about this. joining me now is the director of the florida program for shark research, george burgess. good morning. >> good to be with you. >> a column for cnn.com you said that we should be careful about overstating this threat about sharks, writing, before we start killing sharks, let's all relax, shark bites are few and far between, they occur for reasons overlooked amid the breathless broadcast and suspenseful scenes from "jaws." are we going overboard in the media or is there a legitimate fear a shark attack may not be as rare as it seems these days. >> certainly legitimate fear in

north carolina, where we've had seven attacks in three weeks. it's an unusual circumstance. obviously, there's a reaction needed in that area. the problem is sometimes folks have taken that north carolina bit and turned it into the entire united states. >> all right. but let's talk about maybe why this is happening. i'm understanding that the conditions at the moment are kind of a perfect storm for sharks with warmer water, drought conditions, higher salt levels. more people in the water. so it's almost like, you know, odds are stacked against the swimmers. then again, think of the time this is happening, people at this time of the year, always more people in the water, waters are getting warmer, some say climate change is contributing to this. is this unusual anymore or the new normal? >> a little bit of both i guess. it's unusual because this has never happened in north

carolina, per se, and it's the first time that that community's had to react to a series of attacks over a short period of time. put it in perspective, florida this year already has seven attacks. so we're not hearing any kind of an uproar here. it's because we've dealt with that in the past in -- it's not a story. but one thing is going to happen, and that is there are going to be more attacks year in and year out, simply because the human population continues to rise and with it a concurrent interest in aquatic recreation. one of the few things i as a scientist can predict with some certainty is more attacks in the future because there's more people. >> that is scary. and i just started surfing, so i may dial that back a bit knowing that. let's, for a quick moment, talk about the guy in florida fishing who we saw when a shark caught his fishing line, he didn't want et shark to get the best of him

but found himself flipping out of his kayak into this shark infested water. if someone were to find themselves face-to-face with a shark what can you do to survive? >> well, first of all, i'm going to ask you to restate shark infested water. it's shark inhabited water. sharks don't infest. that's their natural environment. second of all, the point i'd like to make, we classify it this incident as a stupid human trick. eventually evolution will take care of that itself. that said, if you're face-to-face with a shark in the water and it's actually approaching you, pop it on its nose, they have a sensitive nose. they'll most likely veer away, and you can use that extra time to get out of the water. but just remember to hit very accurately because just south of the nose is the mouth. >> wait, did i hear you correctly, tap on its nose? >> yeah. more than a tap.

as hard as you can hit. >> that's if it's face is right there. but you're better off trying, right? >> yeah. i mean, you're asking for last case scenarios. there's even a -- if you're in the mouth of the shark, claw at its eyes and its gill openings, openings behind the eyes. both of those are sensitive and some experiences demonstrated that if you're clawing in the eyes, they'll let go. >> all right. fight for dear life. george burgess, thanks for your perspective on this. >> good to be with you. >> heavy security for a day of se celebration. huge crowds gathering across the country with a major law enforcement presence greeting them. live in new york and washington. plus -- the u.s. women's national soccer team looks to knock off the defending world cup champs and take home the trophy. >> i'm not going to have if they have a shot. i'm going to ask how good is

imagine that it's 2011, you fought your way into the world cup finals against japan, lose the lead twice, suffer a heartbreaking loss. well, there are still 13 players left on this u.s. team who were part of the team that suffered that demoralizing defeat to japan in 2011. now, four years later a chance to redeem themselves. all-time american goal scorer abby wambach says the japan loss still haunts her to this day but the team can't focus on revenge alone. listen. >> heartbreak never goes away but now we have an opportunity and it's not about revenge or avenging that loss. we don't overlook japan for one second because they are very, very organized and good team. >> reporter: there you have it, guys. cannot wait for this to get going. action tomorrow 7:00 p.m. eastern. it's going to get cranked up, calling it a virtual home game for the u.s. i can confirm, a lot of red,
