Cameras on my mind

Cameras are on my mind. Screw google glass as a plaything for people addicted to the digital teat... how about putting a small POV camera on EVERY police officer in America. Every gun, every badge, every dash. Camera, camera, camera. I can't think of a good reason anyone should object. I want to trust the police, I want others to be able to trust them. But the problem is they are fallible people just like all of us. No amount of training will solve every problem when people are thrown into the mix with all their flaws. I know some efforts exist to make this happen, I am going to look into them and see what the pros and cons are.
