OKLAHOMA CITY - Police checkpoints are often controversial, but now they may be getting even more so after an anti-checkpoint group has offered a prize for video or other proof that the police are violating citizens' rights.

The site Copblock.org is looking for content that "demystifies" police checkpoints and they're offering an HD video camera to the winner.

"My advice is always [to] pretend you're being recorded. Somebody is always watching in this day and age," said Fraternal Order of Police president John George. 

George says police realize they may end up on camera at some point, but antagonizing an officer into losing his cool so you could win a prize may be dangerous.

"You don't want to bait the officer into something and you don't want to do things with your movements or your actions that make officers think you're doing something illegal," said George.

Even defense attorney David Slane advises against it. He says participants could be the winners of a night in jail.

"When they may be well-intentioned on sort of checking the police and not letting them get out of hand, they may be giving people bad advice and they may be [themselves] arrested for obstructing an officer in the performance of their job," said Slane.

The Oklahoma County Sheriff's Department does conduct checkpoints. The OKCPD does not.  News 9 is told it's because it is too manpower intensive.
