Who will guard the guardians?

From Cory Doctorow at Boing Boing Blog:

A CBS undercover reporting team went into 38 police stations in Miami-Dade and
Broward Counties in Florida, asking for a set of forms they could use to
complain about inappropriate police behavior. In all but three of the stations,
the police refused to give them forms. Some of the cops threatened them (on
hidden camera, no less) — one of them even touched his gun.

officer: Where do you live? Where do you live? You have to tell me
where you live, what your name is, or anything like that.

tester: For a complaint? I mean, like, if I have —

officer: Are you on medications?

tester: Why would you ask me something like that?

officer: Because you’re not answering any of my questions.

tester: Am I on medications?

officer: I asked you. It’s a free country. I can ask you that.

tester: Okay, you’re right.

officer: So you’re not going to tell me who you are, you’re not going to tell
me what the problem is.You’re not going to identify yourself.

tester: All I asked you was, like, how do I contact —

officer: You said you have a complaint. You say my officers are acting in an
inappropriate manner.

officer: So leave now. Leave now. Leave now.
