They call it "cop blocking," and it's a growing trend targeting law enforcement. Essentially, it's when a third party gets involved in a situation involving law enforcement, such as a traffic stop, to act as a witness and record it on video.
Since the public outcry in Ferguson and New York, this movement is getting a lot of attention, and police are warning that it can be very dangerous. Examples of so-called "cop blocking" have been pouring onto the Internet in videos since 2012. You can see all the videos here.
Hudson Police Chief Marty Jensen learned about "cop blocking" quickly. One of his officers pulled over someone for speeding Wednesday night on Carmichael road, and a car driven by 26-year-old Aaron Meulemans stopped in front of them.
"Initially when she made contact with the driver he told her to go away, twice," Jensen said. "That's all he would say. Then finally he rolled his window down about an inch and a half and said he was 'cop blocking' her."
The officer then called for backup, Meulemans got out of the car, resisted arrest, and ended up being tased by police. He then landed himself in jail. Investigators never found a camera -- so his intentions remain unclear.
"They [police] are already concerned about who they are dealing with in the car," Jensen said. "They also have to watch for traffic going by and now you've got this third person who is interjecting themselves into this environment."
Andrew Henderson runs the Minnesota Cop Block Facebook page, and said various versions nationwide are about holding police accountable through video and the court of public opinion.
"We don't hate law enforcement, "Henderson said. "We don't want to stop them from doing their jobs. We just want to serve as a witness to the interaction."
Call it "cop blocking" or simply interfering with police, Chief Marty said safety has to come first.
"All we request is if you want to film us, do it from a safe distance," he said. "Don't try to interject yourself in the incident whatsoever."
Fox 9 tried to contact Aaron Meulemans about his arrest, but have yet to hear back from him. He's expected to be charged with resisting an officer and disorderly conduct.
