you, also nearby. you speak german. what are these police shouting at the crowds? reporter: the police, they re basically using the intercom systems, which i think are probably actually on the water cannon trucks that you see right here. remember, atika was saying that some of the water cannon trucks had turned around. they re coming to us right here and what they said is look, this is the police speaking, and we need people to move out of this area. otherwise the police is going to kick into action or police action will start. i think those were the exact words that they were saying. so that s basically they re every time they make a move, the police, they make an announcement beforehand and that s sort of what they re announcing right now. anybody who s in this area right now is going to be subject to some sort of police action. and, you know, wait and see whether or not something like that kicks off. usually it takes a while and they ll sort of let people stay here for a while,
germany where you have to warn people of police action before the police actually goes into action. they re going to keep making those announcements and every time they make the announcement, they also always name the time of day that it is at that point. now the crowd is cheering, go away, go away to the police. and maybe we can move forward just a little bit to see if we can sort of get a little closer. that s sot medics coming through here as well. make sure that we don t get too close to this. but yeah, as you can see, it s really we can see the water. standoffish sort of environment at the moment. we can see the water. we can see the people with their cell phones, you know, filming it. and let me just say, you know, i apologize for the middle finger that just popped up on tv, but listen, it s a frenetic environment and this is folks, this is live tv. for people, though, fred, who are just tuning in, again, this is the g20. several days there in hamburg, germany. who are
so, shoulder i mean, so we don t know how certain the u.s. would be, then, in terms of having the u.s. knock down a missile. no, not at all. you know, the reality is, tests cost sometimes up to $200 million, so the system just can t be tested the way that you would want for a statistical confidence. and so the reality is there s a system in place, you know, it s designed to do this job, you know, people work very hard on it. but you just you re just never going to know. this isn t the kind of thing that you want to rely on. the way the pentagon plans to do it is to fire four or five intercepters at every missile and just hope if you figure everyone is 50/50, you get lucky. wow. i don t know how americans would feel about those kinds of odds. i mean, in this time, jeffrey, of uncertainty, is there anything the u.s. can do to prepare for any sort of worst case scenario? well, at the end of the day, you just have to try to look at
i m going to guess those aren t decorative fireworks. maybe you have fourth of july of your brain. i think that s perhaps law enforcement as you point out, some sort of flash bang or something set up in the sky. reporter: unclear, though. it looks like they re coming from more of a rooftop angle so it s not the yellow it s not the orange tear gas we saw earlier from the flash bangs. it is different than that. so again, it s dissipating, and again, we should point out, still relatively peaceful as far as these protests go. jeff zeleny, thank you. from hamburg, still light out, nearly 9:00 at night. i think the sun doesn t even set there until around 10:00. let s talk more substance as we pivot back and forth between the pictures of these protests and these all-important world leader meetings. i have standing by matt, author of angela merkel, europe s most influential leader and political science professor at
still a number of protesters sitting in the crosswalk so it s going to take them a while to move them out. i think that s why they brought the water cannon as a sort of last resort to push them out. atika, help me if i can just jump in. help us understand, for people who don t know hamburg and the area, how far are these protesters actually from the summit itself, from these high-level meetings? reporter: this is about three kilometers from the messa, which is the conference center with the g20 summit is happening. so it s not that close. but it is close enough to do a march to and that s what they were planning to do. this part of town is known for its leftist protest activity, so when the g20 summit was put here, people said residents here said, it s going to get crazy. this is exactly what s going to happen. and that seems to be what s turning out. we re going to turn the camera up a bit so you can take a look and see what police are doing. but these are the kinds of running c
