This happened in Hammond, Illinois, and allegedly was due to the drive not wearing a seatbelt. Clearly the cops had no interest in sympathising with this poor guy. Luckily his son caught it on camera. They smashed his window, spraying the daughter with glass, tased the father and pulled the man from the vehicle. They drew a gun on him at first and called him a dumbass referring to the rank on his shoulder. The officer was involved in two prior excesive force lawsuits that were settled by the city and paid out taxpayer money. The family has filed charges against the officer. Here is an excerpt from the article about further abominations of police actions in Hammond:
Hammond police prompted further headlines recently in unrelated cases. One federal lawsuit alleges that an officer barged into a family gathering and shot a pet in the face while it was secured inside its own yard, while another alleges that an officer was filmed whipping a police K-9 and lifting the dog off the ground it by its leash. In both cases, officers were supported by the department, and were not penalized in any way.
