Night sticks are what got the LAPD in trouble over Rodney King.
We (When I was a Deputy) never carried PR24s-nightsticks).. We DID have to get Pepper-Sprayed before we could carry that though :p and ASPs were just coming out when I left (and came here).. so no idea what training there is/was for that.
From what I see here on FR, not sure I would want to be an Officer anymore :/
