Use of Force Criticized in Protests About Police Brutality Associated Press As protests grip the nation, officers have doused crowds with pepper spray, struck protesters with batons, steered police cars into throngs, shoved demonstrators and screamed curses. Some police action has been directed against people smashing windows, breaking into stores and burning cars, but many find other instances more difficult to understand -- like the elderly man knocked over by police as he walked with a cane on a Salt Lake City sidewalk. The protests began after the May 25 death of George Floyd, a black man who died in Minneapolis after a white police officer who is now charged with murder, Derek Chauvin, pressed his knee into Floyd's neck for several minutes even after he stopped moving and pleading for air. Now, some are questioning whether tough police tactics against demonstrators are actually making the violence worse rather than quelling it. While the protests and subsequent police interactions may be shocking to some, many African Americans aren't surprised because they've endured police brutality for decades, said Chris White, director of the Detroit Coalition Against Police Brutality, "What's happening, it's the way American society has always been," White said.
