When I tell people I'm a court reporter, they ask me what I do; I tell them I swear people in and watch them lie.
Sworn testimony is only a little better than unsworn testimony.
Actually, unsworn testimony is not as INFURIATING as sworn testimony, because your head doesn't blow off when you know they're lying under oath. :-)
My hat is off to those on patrol, while, on the other hand, I would like very much to arrest some detectives.
We should.
There's every incentive to lie in the courtroom and only the vaguest threat of a penalty.
