Consider this: I'm on the clock and my boss is watching me. I'm in court before a judge giving testimony. There are 3 choices, lie, truth, 5th.

Truth: I lose my job and am possibly jailed for gross dereliction of duty/being an accessory to an assault.
Lie: I am committing perjury and if caught go to jail
5th: I am constitutionally safe from the court but lose my job because I'm obviously guilty as hell.

Granted, gently caress these guys, but I'm just making the point that the situation is a little different than if the same law covered non-police. Not that it should exist, it's bad, but it's a little interesting.
