Zero, the same percentage that criminal activity and criminal apologists are acceptable to me.
I assume you wouldnt mind of a cops lie put you in jail?
You know what is said about people who ASSume, don't you? Do you believe being an ass is becoming?
Hows that badge taste?
Never tried to eat one. Have you?
Good riposte. I'm not sure I could have thought of something that clever. I'm not suggesting you eat them, not when mere licking gives you the flavor.
Experienced court observers put the number of cops who lie in court at over 50%, easily. People are sent to jail for that and told they got off easy, ruining their lives. I agree 0% is the acceptable answer but it's way, way higher than that. It's been said an encounter with a cop is like landing a plane: it's a good one if you can walk away from it. When I was a kid being a cop was a considered noble profession. With today's SWAT teams and RICO, it's become a glorified street gang with fancy uniform and jackboots bent on theft of your assets.
In today's police state, if you're a victim of a crime you are better off if you "take care of it" on your own. Inviting a cop into your home to discuss a crime on you is inviting a cop to inspect it for criminal activity without a warrant.
