DETROIT – A man who was seen on video being punched multiple times in the head by two Detroit police officers said he was asking them why they took down his friend. Darius Bell, 25, told the Local 4 Defenders he demanded officers tell him why they rolled up and took down Kenneth Pierson. Bell said officers used a Taser on him, and he was worried they were going to leave him with serious injuries. In the video, Bell tries to show officers a card of his family member who works for the Detroit Police Department. Detroit police officers said they were on patrol and could see a gun in Pierson’s waistband.
