Do mandatory body cameras actually reduce police brutality?

Mandatory body cameras can help police be nicer and less likely to hurt people if they know they're being watched.

Imagine you’re playing a game with your friend, and there's a rule: if you shout at someone or push them, the whole class knows about it. That makes you think twice before doing something mean. Body cameras work kind of like that rule, they let everyone see what happens during a police stop.

Think of body cameras as little video recorders that police wear on their chests. When a cop uses a camera, people know someone is watching them, just like when you're playing a game and the teacher has a camera in the classroom. That can help cops act more fairly, because they might not want to get in trouble if something goes wrong.

But it's not magic, sometimes cameras don't work right, or people forget to turn them on. Still, most of the time, having cameras helps make things better and gives everyone a fair chance.
