Caught on tape: Adults behaving badly

>> have been ordered to appear in court, suspected of encouraging and recording a fight between two young boys . this apparently is just the latest example of adults behaving badly . the story now from nbc's ron allen .

>> reporter: someone was so outraged when they saw these pictures online, they reported them to police . the children are possibly 5 to 8 years old, police say, and the video was shot by an adult.

>> what is most disturbing is the fact that there are adults that are nearby that aren't stopping it.

>> reporter: in fact, another man appears to move some children out of the way so they don't block the camera.

>> move. back up.

>> move.

>> my professional opinion is that this is a form of child abuse .

>> reporter: these days, it is not hard to find video of parents behaving badly . like that minor league hockey coach in vancouver, canada. he says he slipped during what was supposed to be a post game show of sportsmanship, when his foot seemed to trip a 13-year-old player on an opposing team. the player broke his wrist. police are investigating whether to charge the coach. and there are cases of parents caught allegedly encouraging their kids to fight. like this mother of three from long island, new york, who police say took her daughter to a schoolyard to confront several bullies. the mom has said she took action because neither school officials nor police were willing to get involved to protect her daughter. in florida, police say this father was caught on tape encouraging his son to fight another teen.

>> knock him out! knock him out!

>> reporter: the dad said he regrets some things he's heard saying, but said he, too, was helping his son fight back against months of harassment.

>> two wrongs don't make a right. this is the worst kind of parenting there is.

>> reporter: back in california, it didn't take long for an anonymous tipster to let police know where that fight had taken place. two brothers, including this man, who had posted his own picture along with a video were issued citations to appear in court to explain. a fight that ironically only stopped, police say, when a child stepped in to break things up. for "today," ron allen , nbc news, los angeles .
