Anyone who works retail knows that you can and probably are being videotaped. And if you do something wrong, like steal something, you can bet you'll eventually be caught and those tapes will be used against you.
Unfortunately, some police officers across the United States seem to think that they should be above the level of accountability of the average citizen.
