all right. stay right here, we've got a busy morning of news. >> next hour of "your new day" starts right now. security dominating this fourth of july holiday. law enforcement out in large numbers and they are asking everyone to be vigilant this fourth of july. plus, shark attacks. ten attacks down the east coast already. should people be afraid to go into the water? and checking out this sign telling cuffed passengers in the police van to enjoy your ride. a city that has a real struggle between police and its citizens in some respects are now investigating this. good morning, i'm alison kosik in for christi paul. >> i'm victor blackwell. >> as many celebrate the fourth of july, officials warn to be

individual up lent. >> new york, new jersey, washington ramping up security after bringing in extra officers, spotters and sniffers. snipers as well as officials warn celebrations could be the target for terror attacks. >> the concern is being felt overseas as well as embassies and consulates meet with security teams and review their efforts to stay safe. in fact, one u.s. air base, one u.s. airport base in england actually called off this celebration today because of increased security threats. so far there haven't been any specific threats but there's been chatter leading up to our nation's holiday. we are on the site of a major fourth this morning. good morning, sunland.

>> reporter: good morning. while the major security presence is nothing new for the washington during the fourth of july, but many are on edge jolted by the bulletin from the department of homeland security warning about potential attacks by i just. the big concern with no specific threat is the potential lone attacks. this is something the d.c. police chief is taking very seriously, especially as they patrol here on the mall today. >> you think about the significance of the holiday, the significance of washington, d.c., and honestly, in all honest to the best of my recollection we think about that every single day. not just on independence day and july 4th, but this is what is going on around the world. the radicalization and some of the other incidents we have seen, this is something we don't take very lightly.

>> reporter: and here in d.c. there are special patrols today at washington landmarks and also an increase of to heavy police presence in seen and unscene ways as well. there's also a team here monitoring websites and watching out for any watch words. >> sunlen there from the national mall, thanks. and we are covering security efforts in new york. boris, good morning to you. i know this living in new york, security is tight on most days, how is this different with the holiday? >> reporter: there's a very large law enforcement presence here at penn station, about 42 million people are traveling this holiday weekend. so officials are focusing on travel hubs like here at penn station. yesterday the governor of new york announced he was adding extra patrols and staff to the emergency operation center. in addition, law enforcement told us they have snipers and

spotters in key strategic locations around town, watching crowds for any kind of suspicious activity. and teams are scanning for explosives and rad owe active items from sea and air. officials say they have to be ready for any kind of attack. >> you always have to take into account what is the unknown threat. what is the possibility out there, whether it is lone wolf or focusing on isis. the al qaeda peninsula network has not gone away, so we are focused on that, too. what we ask of our officers is heightened vigilance and heightened counter intuitive awareness. >> the governor is also asking new yorkers to stay vigilant. if they see anything suspicious, call law enforcement right away. we have a very big prenz here at

penn station. >> thank you for that report. cedrick, we see the big cities have resources. the smaller towns, even outside of atlanta, they have to determine which landmark to go to. how do they make that decision? >> really in a big city or moderate sized community or small community both state, federal and local are all going to be working together. for example, you take here in de kalb county one of the most famous, beautiful parks in the country. stone mountain park. we are expecting over 100,000 people out there today and we'll have resources. you are going to be accompanied by local, federal and state law enforcement.

even in the city of atlanta, you have the peachtree race which is going to be a huge event. and other events going on across the country as well, but all resources are going to come together to keep the community safe. but it is very important that i remind americans that one of the best resources we have are the citizens themselves to keep on alert and vigilant. >> that is always difficult for some people to do. in some people's words, snitch on a neighbor or a friend or someone who you see in a public place. >> well, you can't look at it in terms of snitching. you have to look at it in -- >> some people do. >> and some people may, but the fact of the matter is we must be in this community and this nation and this united states together. because we all know we have outside of horses trying to do harm to hurt us. this is a time so in our history, more so as we move into the 21st century, is that as

communities continue to work together with our local, state and law enforcement partners, our tribal partners across the country, it makes a safer nation and a safer america. as we celebrate today, it is just really the hallmark of why we are here. this is wonderful country and wonderful people. the diversity of it, we have a wonderful history in this nation and as people move forward and we do harm or they try to harm us, we have to move forward with this. >> if a person has a hatchet or gun, they can go up to that person as a statement against the government. what -- and you're a psychologist as well, what is that level of preparation, especially on a weekend like this for law enforcement? >> well, for all of us.

certainly, we have heard the threats both to military and law enforcement as well. but for all of us that are in the united states, we need to take care of our citizens that we are sworn to become. yes, it becomes taxing, if you will. and it does raise a little anxiety. but if you think about it, the men and women aring doing this in a way we are all proud of. and so is our military. any time anyone wants to threaten military personnel and all of us at this nation, we must stand with them and be vigilant together. and i'm more confident that is going to be the case. it has been the case of open teams in this case.

okay, that's safe to say that's pretty terrifying there. video of a man swimming for his life after a shark flipped him from his kayak in the middle of the ocean. ben was fishing for grouper when the shark knocked him over. he quick swam to a support boat, but for some reason, he's crazy. he hops back into the kayak to finish what he started and unhooked the shark. he spoke to cnn last night about his adventure. >> i made it to safety and we flipped the kayak back over. at that point in time i felt like the shark had won the battle. i thought i was winning but when he flipped me over i felt like i

lost the battle and it was an indication to hop back in and finish it off. it's like when you hop off the horse, you better hop back on. >> he didn't let the experience shake him at all as he was back in the water yesterday. this incident comes at a time when the u.s. is on heightened alert for shark attacks. the east coast has had ten attacks total. we are live along wrightsville beach right now. what is the risk this year compared to an average year? >> reporter: it seems to be the perfect storm for this to happen. sharks have been spotted closer to shore. i was out with the locals talking about this, what seems to be an active shark bite season, and some say it is not a

general concern but certainly something on everyone's minds here. a rash of shark attacks off the carolina's coasts. this year already at least ten attacks, that's nearly double the yearly average for north carolina and south carolina in one month. another 11 attacks have happened in florida. a shark bite so frequent they could surpass last year's totals in the united states. >> it actually must have come in the wave because i didn't see anything. >> reporter: this survivor tells anderson cooper he was swimming in north carolina's outer banks with his 8-year-old son when he was attacked. >> i started shouting, shark! shark! everyone out of the water! at the same time i'm punching the shark to get him away from me and went over to grab my son. >> reporter: a contributing factor? perhaps a perfect storm of environmental and biological variables. some sharks feed on turtles and small fish close to shore.

scientists say drought conditions can also play a role among other things. >> certainly warm water this year, higher salidities. there are more turtles in the water and that would bring on more sharks. >> reporter: too close for comfort for the fourth of july weekend surfers and holiday goers. >> the other day we saw a 5-foot sand shark and it was within 8 feet of me, but it stayed out in the water. it's his natural habitat. it is hanging out there and we are in it's home. so you have to be aware of your surroundings and be careful. >> now do you think there's a high probability of being bitten by a shark? think again. the likelihood of you being bitten by a shark is like 1 in 11 million. you are more likely to be struck

by lightning or become president of the united states. even still to avoid that happening, swim in groups and avoid dawn and dusk when most injured. >> nick valencia, thank you so much. how big is the threat for shark attacks? should you be afraid to get in the water or are you safer than you think? joining me is anna casa grande. andy, i have to ask you this, first of all. i'm new at surfing and get out in the water to surf. i'm a little afraid hearing of the reports of the shark sightings and attacks. is it rational to feel this way or is the threat as big and real as it seems? >> i think it is irrational. the likelihood of anybody halling is pretty low. yuchb hear the term shark-infested waters. a lot of people have a good

grasp on what is happening and there's an increased number of bait fish, drop conditions and increase i increasing in shark attacks. you are way more likely to get killed in a car crash on the way to the beach or mugged or whatever it is. it is tough for people because it is a really traumatic and sensational idea to be consumed orbiten by a predator. but it's the fact of life. sharks live there and we are the visitors. i wouldn't worry about getting knocked out by your surfboard if you haven't learned yet. >> i haven't been mentioned yet. is this becoming the new norm? everyone says it is unusual to have this many shark bites, but the conditions of the water, climate change, you name it, is

this the new norm to get used to? >> i don't know if i would say norm, but the increase of the attacks in north carolina and south carolina is unsettling. but worldwide, ever since humans entered the ocean sharks have investigated, bit, attacked, whatever you want to say. they are simply predators. i wouldn't worry about it. if it is mercury water and see bait fish, you just get that sharky feeling, stick to the swimming pool because it is common sense. it's just like walking down a dark alley where you think you might get mugged. sharks are not malicious but predators and just reacting to instinct. if the water is murky or they see splashing, they may come to see. none of the attacks have been fatal, so most likely mistaken

identity. we really do not want to demonize the sharks to say they are shark infested because that's not the case. >> i do not want the sharky feeling but i may just go back in the ocean to surf. thank you very much. pretty frightening at a fireworks display. whoa, what is going on. >> no fireworks! >> whoa! >> when they start going off on the ground, you know there's a problem. there are people who have been injured this morning. we have details in a moment. ♪ whh diabetes, steady is exciting. only glucerna has carbsteady, clinically proven to help minimize blood sugar spikes. so you stay steady ahead. you forgot the milk!

work working with or inspired by isis attacking is high. and we'll bring in retired lieutenant colonel tom kernis and tom fuentes. we'll start with tom. how do you deal with the vulnerability inherit with security like the national mall or the national airport? >> i think the only way to protect us is with good intelligence that an attack might occur. that somebody is going to do something bad to try to find them before they penetrate a hard together. which means you don't have to go through a check point.

when they approach a check point and go inside, that becomes the harder target. but you have to get to the hard target areas being protected and in that case the mess respond you in a soft target. >> the british air base used by american airmen canceled their fourth of july plans. what does this mean? >> a lot of people are taking cues from the evidence of what happened in the u.k. they are getting their intelligence from that piece as well as in the state. the state department goes through this all the time. this is a new more faller

are or parents, why is that important? >> it is very important any time you have a homicide investigation. that is what this means, the quicker they find the caretakers the quicker resolve in this case. what is very important is the autopsy itself become from the victim, it is a very sad case. there in the community where you have the d.a. and police asking people in that community around the country if a child that you would normally see that would show up, if for someone reason they are not there.

there's an investigation underway in baltimore, specifically within the police department there, after photos surfaced showing a police van sign that one official describes as concerning. it reads, "enjoy your ride because we sure will!" that's reference to the rough ride, the claim that police drive recklessly to injure suspects. this is of concern after the death of freddie gray who died in april while in police custody. gray was not buckled in to the seat belt there in the transport van. a violence of protocol. we'll talk about this, bernard carey, the former new york city police commissioner is here. good morning to you. >> good morning to you. >> here's what we have to start with, the authentication of this photograph. the baltimore state police say

they cannot authenticate the photo. however, our affiliate reported that the photos were authenticated by the police department officials. why seemingly this backtrack? >> well, i don't know why the backtrack. the sign itself is just stupid. i don't know who put it up there and i'm sure they -- if they follow protocol, they should be able to figure out where the signs came from. the vans should be inspected by every cop that is assigned to them before and after their use during the tour. they may also be inspected by a first lane super visor. i'm sure you won't find where they came from.

however put them up is just stupid and a moron. >> the stickers have to line up and are all placed properly. i wonder what the context is for you depending on the it was pre-freddie gray or post-freddie gray when this was put on the door. >> well, victor, it doesn't make a difference to me. because in a circumstance like this, if you have an incident where somebody gets hurt in the back of the van, the assumption is it is all about the rough ride. then you turn the suspect in and it is just stupid. >> at lot of people believe the six officers who were charged should have been charged. but we hear from the police chief who says they should not

have been. explain the sense of resentment that comes out of the system or something like the turmoil we have been seeing. >> the cops were bashed in the aftermath of this baltimore incident. you know, you've got cops out there that are angry, upset, they feel like they are not backed and supported by the administration. maybe that's where the signs came from, but post-freddie gray, whoever put the sign up is making it worse with the perception that it is all about the rough ride en. and the reality is that it isn't and shouldn't be. >> how does this likely play into the investigation? >> honestly, i don't think it

does. i think the doj -- you can say whatever you want about this, but it needs to be taken seriously. >> thank you for being here. coming up, we'll talk about how this can trigger episodes for veterans with ptsd. and tomorrow marks a critical day for the future of greece. this is a referendum on a bailout set to happen. the big vote is on its way but the nation is deeply divided. we'll break it down, next.

good morning. greece is deeply divided ahead of a critical vote tomorrow on a referendum for a proposed new bailout. the referendum taking place against a backdrop of protests. this one that you're seeing is against the measure drawing an estimated 20,000 people in athens last night. the same number turned out for a rally in favor of the measure that was nearby. cnn's richard quest is joining us live from athens. what do you think, richard? is the vote going to go yes or is it going to go no? >> reporter: it is way too close to tell. the opinion polls have now finished. under the law, there's no

opinion polls before the vote of the day or the day before. and the numbers are roughly 50/50 right now within the margin of error. there's a large percentage of people undecided. what this is really coming down to, alison, is the fear factor. on the one hand, the government says people are being made to fear saying no. but on the other hand, the yes vote says people are being made to fear the european option. whichever way it goes, one thing we can say absolutely certainly, all economic decisions for this country and the future will be unpleasant. greece has got some extremely tough times ahead. >> does a no vote against the austerity that in this referendum, does the no vote mean greece would leave the eurozone. is that an automatic? >> reporter: no, absoluely not. let me be totally clear about this. and that is part of what the

prime says. he says that the yes could mean scare monogoring, telling people voting no would mean this. it is not an automatic exit from the eurozone if greece votes no tomorrow. the government says that will be the mandate they need to go in hard to negotiations with brussels. >> richard, why should americans pay attention to this referendum? >> reporter: oh, i think you pay attention for all sorts of reasons. not only because greece is a democracy, but here's a democratic vote over the future of this country. but if there are major disruption in greece, it will transmit itself to the eurozone, the largest trading partner of the united states. and as president obama himself said in the white house when he

was with the president of brazil, he said, you know, he's spending a substantial amount of time over this. because if there are problems with the economic situation in europe, then yes, it will hit america, too. >> richard quest, we'll be watching the turnout of that vote and what the answer is. thanks. people across the country are being asked to stay vigilant this fourth of july. officials are warning of lone wolf terror attacks that could put party goers at risk. we'll tell you what to expect as you get set to hit the streets. a y i can offer you no interest for 24 months. thanks to the tools and help at experian.com, i know i have an 812 fico score, so i definitely qualify. so what else can you give me? same day delivery. the ottoman? thank you. fico scores are used in 90% of credit decisions. so get your credit swagger on. go to experian.com, become a member of experian credit tracker,

all right. here's a look at storie making headlines this morning. >> a pilot was killed when his medical helicopter crashed moments after takeoff. witnesses say the helicopter spun uncontrollably before crashing to the ground and exploding. the two other crew members on board had significant injuries. they remain in the hospital. the ntsb is investigating. and it's going to be a busy july 4th for a half dozen candidates. they are spending independence day trying to win key votes. jeb bush, marco rubio, chris christie, all spending the day's company in new hampshire. meanwhile, democratic challengers, bernie sanders and mark o'malley are in iowa. also, two big competitions this holiday weekend other than the political ones. today is the annual hot dog

eating contest. >> i love this. don't love it, kidding. >> eating as many as possible. this is nathan's eating contest. joey chestnut going for his ninth straight victory. >> i covered this once and the smell i'll never forget. if you can't stomach watching the gorging, you can cheer on the u.s. women's soccer team taking on japan for the world cup tomorrow. that's where coy wire is outside of the stadium in vancouver. how is it looking, coy? >> reporter: good morning, alison and victor. it's great here. we'll talk about the game plan. the most important part of the game plan for the u.s. isn't how they approach the match that strategically but how to not overlook japan. they beat their number one ranked german team, so it would be easy to start thinking they got this locked up. that would be a huge mistake. japan is the reigning champ and they have proven they can beat the u.s. as the underdog as they did in the last world cup final.

and speaking of dog, guys, you touched on it. we'll flip the script real quick. the game is not until tomorrow, so the big sporting event today is the nathan's famous eating hot dog contest. joey chestnut is the number one competitor eater in the world going for his ninth mustard belt in a row. he holds 38 competitive eating records from hot dogs to apple pies. he looks to eat his weight in hot dogs. i read how the guys put on 20 pounds in a competition and then i prompt ly -- lost my appetite. >> something tells me they don't gain all that weight. >> just the smell of hot dog water is enough to end that idea. >> that's why you put it on the grill. there's no water involved. >> you have to burn it.

burn it. >> little sauerkraut and mustard. >> there you go. thank you for watching this morning. so much to tell you about. >> "cnn newsroom" starts now. america on alert. security beeped up across the country. many are on guard against a potential july 4th fire attack. and a fireworks malfunction and nine hurt in a misfire. a shell explodes in the launch tube instead of in the air. and swimmers are weary along the carolina coast after ten shark attacks already this year. that's almost double the average. why more sharks could be coming closer to shore. good morning. i'm alison kosik in for christie paul. >> i'm victor blackwell. it is 9:00 a.m. and it is good to have you in
