Chicago cop caught on video taunting black men -- and bragging about killing people

An unnamed Chicago police officer is under investigation after a social media video of him saying he likes to "kill motherf*ckers" went viral.

Chicago's Fox 32 reported that the city's Civilian Office of Police Accountability opened an investigation into the officer after a social media user filmed the officer in full uniform making violent comments to the person recording.

"I kill motherf*ckers," the officer, who was in an unmarked car, is heard saying in the beginning of the video before telling the person recording to not film him and suggesting he may arrest him for "walking illegally" in the street.

The officer then denied that he made the comment about killing people before telling the man recording that he doesn't "give a f*ck."

After driving down the block slowly in pursuit of the man recording, the officer then got out and began following him and his friends on foot, telling them that "Illinois is a two-party consent state and I don’t consent to you recording me."

As he got closer to the group of young black men, the officer accused the person recording of hitting his shoe and appeared to goad them, suggesting the group call his sergeant. He then told the young man to get out of his way and tried to grab his phone.
