But I know from friends that those same police officers become totally different people when in a different environment (particularly uptown and in poorer Brooklyn neighborhoods) and especially when dealing with people of color. There is bullying, there is haughtiness, and there is often a complete lack of respect.
Video cameras can change that. The knowledge that any citizen can file a complaint about an unnecessarily hostile interaction means that police officers will begin to act the way they are supposed to, as the only members of our community to whom we grant a monopoly on the legitimate use of physical force.
I also believe that video cameras will have a positive impact on police, increasing the respect they receive from the community and their self-respect, and enabling them to prove that they are often in the right around contested confrontations.
