<<So the argument that they are on the public payroll doesn't hunt.>>
I think the fact that they're on the public payroll means that their boss John Q. Public has a very good claim on seeing how they perform their public duties and interact with the public. I wouldn't think that anyone has a right to film Donald Trump's secretary at work because she's not on the public payroll.
<<When a person becomes a policeman or fireman or meter reader do they give up their rights as citizens?>>
Stay with the cop, because he's given a gun and a club and a limited authority to actually do some damage to other human beings with them. I think realistically this man has to be held more accountable at the expense of some of his privacy rights because of the damage he can do. Sure he's got a right to privacy, but the public has the right not to be fucked up the ass with his nightstick.
Police brutality is real, with real victims, with serious, sometimes fatal damage. So if you hold the cop's privacy rights as sacrosanct as the meter reader's, you've done an equal job in both cases of protecting privacy rights, but in one case with a major cost in public safety and in the other with no cost to public safety. If you believe that public safety (freedom from arbitrary police brutality) is a valued public interest, then you have to wonder why is there no trade-off at all in the cop's case? You don't NEED a trade-off for the meter-reader, he can have 100% protection at no cost to public safety; is it right to give the cop the same 100% protection, even if it takes a bite out of public safety?
I personally think a lot of cops are arrogant ass-holes who will get away with whatever they think they can get away with in terms of abusing the powerless, the homeless, the visible minorities. Sure there are good cops, but they're not the problem, are they? The problem is the bad cops and if cops (good and bad) are taped, the good ones have nothing to fear and the bad ones will get nailed. So what if the good cops' "privacy rights" are infringed? The benefit that comes from that is very important: no more Abner Louimas. Even if it reduces the number of Abner Louimas by ONE, the loss of good cops' privacy was well worth it.
<<Wasn't Roe v Wade about the right to privacy?>>
Not sure. If it was, it was a different kind of privacy. What the woman decides to do with her own body and her fetus is not impacting society the way what a policeman decides to do with his nightstick and somebody's rectum. YOU could be on the other end of the nightstick. I could be. Or my son.
<<Should we limit to guys in uniform or would you extend it to undercover cops and detectives?>>
If they're in the station why shouldn't they be taped? If they're under cover on assignment, wouldn't make sense. How could they not be revealed as cops, thereby abandoning all benefit of being undercover?
