As bad as the outcome of this was, it is not surprising. It is beyond comprehension that a reality crew can follow law enforcement. That should not be allowed under any circumstance.
It has to affect the dynamic of any "raid" or other dangerous situation. A cop should not be thinking about there performance for the cameras.
Also, citizens' right to privacy should be considered. If someone in your family were arrested, would you want this to be entertainment for the masses? Possibly showing your home and family members present. And no, I nor anyone I know have ever been picked up on "COPS", lol.
