Plainclothes Chicago police officers fired nearly 100 gunshots over 41 seconds during a traffic stop that left one man dead and one officer injured, according to graphic video footage a police oversight agency released Tuesday.

Five officers from a tactical unit who were in an unmarked police vehicle surrounded an SUV last month driven by Dexter Reed, allegedly for failing to wear a seatbelt. Video shows the 26-year-old Black man briefly lowering a window and then raising it and refusing to exit the vehicle as more officers arrived, yelled commands and drew weapons.
