Transcript for Celeb Kid Paparazzi
And we're going to begin here with the explosive testimony from some famous parents this week. Out to protect their babies, their young children from the glare of the paparazzi. Their parents are famous, but tonight, they're arguing their children are not. They didn't choose this. This evening here, the pleas from parents including actresses halle berry and jennifer garner. But will it be enough? Here's nick watt. How was your dinner? Reporter: Ben affleck has tried fighting back. . I'm sorry, man. Reporter: Can you blame him? Every day, a dozen photographers follow affleck, his wife jennifer garner and their three little kids. Their daughters have begged for it to stop. Stop taking pictures of us and our dad. Now! Get out! Yeah! Reporter: And now their mom is taking the fight against the tot-chasing paparazzi to the california state assembly. They have a bounty on their heads every day. My 17-month-old baby is terrified and cries. My 4-year-old says, "why do these men never smile? Why do they never go away? Why are they always with us?" Reporter: This week, garner and another leading lady -- I got introduced as halle berry, but I'm here as a mom. Reporter: -- Are fighting for a bill that could land a paparazzo in jail if he, quote, seriously alarms, annoys, torments or terrorizes a celebrity's kid in the process of snapping their picture. Berry has, on occasion, totally lost her cool. This is how you make a living is to harass children because my child is in there. You are. She's at school. Can you leave children alone you idiots. We aren't just whiney celebrities that many times people think we are. They have the right to the take the photographs, as much as i hate it, as much as I hate it that my children are objectified that way. This bill still allows them to do that. What we're asking them to do is to take these pictures with some dignity. I love my kids. They're beautiful and sweet and innocent. And I don't want a gang of shouting, arguing, law-breaking photographers, who camp out everywhere we are, every day, to continue traumatizing my kids. Reporter: These days celebrity kids are everywhere, ON OUR TVs, IN OUR MAGAZINES. Which ones look like their parents? Who's the cutest? Wow, aren't they stylish? Is that one a pawn in a messy break up? Stop taking pictures. Stop the pictures, guys. Reporter: This is the high price celebrity kids are paying for inherited fame, for being born into a hollywood family business. Ben evansted owns the national photo group, a celebrity photo agency in los angeles. 6-year-olds going to school, do you never feel bad for them? Feel bad? No. Do I feel bad for taking a picture of someone that's newsworthy? No, I don't. As long as I'm within the bounds of the law. They're not famous. They're not celebrities. It doesn't warrant scrutiny. It's not appropriate. It's not healthy. Unfortunately, that's not the way it works. The way it works is, if you're in the public eye, regardless of whether you chose to be there or not, you're going to have some attention from the media. And that's where these children find themselves. Get back, guys. Get back. Reporter: And most of these kids, really, really hate it. That scared, little pink bundle is suri cruise. She is prime paparazzi prey. Guys, stop! Reporter: This is totally illegal in, say, england or france, but it is totally legal here in the united states. It's a first amendment right. The intent of the law is to protect these women and actresses from being harassed when they have their children. So I'm always a little leery of any laws that I think ultimately could impact legitimate journalists from doing their job. When I walk up to school with my son and there are cameramen following me -- he has a relationship with the camera that's antagonistic. His class pictures for two years have been this. And I think it's a shame for him. Guys, stop it. You got enough pictures. Reporter: But if a 6-year-old is saying "please don't take my photograph," the paparazzi will not listen to that child, and will continue taking those. They'll take the photograph. Reporter: They'll take the photograph? They'll take the photograph because it tells a story. Reporter: We rolled with ricardo mendoza, an l.A. Paparazzo on the celeb beat seven days a week. There's kelly osbourne right there, right there. Reporter: Where? Right there. Hi, kelly! Reporter: I felt a bit shy too get out the car. Like you're not worthy of it, almost. Reporter: No, it's more that just, I just feel weird getting in someone's face. He says he's one of the nicer guys lurking in the bushes. He never gets closer than five or six feet. He's friendly. And mendoza says he would not, for example, snap halle berry dropping her kid of at school. But just wait until you hear why. The financial gain that I'm not going to get out of that, it's not worth the hassle of hearing her yell at me. Reporter: The pic, he says, is worth only 250 bucks. Okay, but let's say the shot of halle berry and her kid was going to get you 100 grand? I'd take the shot in a heartbeat. I'll take two shots. Hate me for all you like, I'm the photographer. It's the general public. The general public craves it. They want to see it. Reporter: We the public buy these magazines, watch these tv shows. Is that the bottom line? Mendoza has photographed his share of crotch shots and drunkenness and claims it is his duty to document the good as well as the bad. I have to show the foundation of family. That's my defense, and that's the only one that I need. Reporter: Julia roberts, that's her chasing down a paparazzo from the school gates, she does not agree. You can turn your video camera off because I'm going to talk to you about the fact that you're at a school where children go. Turn it off. Reporter: She is awesome. When we do public events, they are very welcome to come and work with us and take the picture in situations when we both agree to do something together. But them running errands during the day or bringing their kid to school, I just don't think that's right. Reporter: Kevin mazur, a celebrity photographer, the kind who gets invited inside, made a documentary about the paparazzi available on netflix. It's called "sellebrity." They're $50, $250, as much as $250,000. I don't know that anything's going to change. Every time I think we have reached our lowest we seem to dig lower even. Stop it. I'm not kidding. Reporter: And neither are these crusading moms. It's not about me. Take my picture. I get it. They're just kids like your kids or anyone else's. And just like you want to protect your children, I want to protect mine. Reporter: That's easier said than done. Even if this new bill she's championing becomes law, it won't stop this, or this. The paparazzi won't stop. It's not me, it's going to be that little joe schmoe with the mobile camera. Those little, those little smart phones now, everyone is a paparazzi now. Good luck! Reporter: Strange as it may seem to some, snapping a picture of a celebrity kid on the street is enshrined in the first amendment. You know, I kind of asked for this life and kind of knew this was part of it. There is a price to fame. Are you willing to pay it?
