Once in fifteen years. It's actually pending right now. I don't want to unnecessarily worry you, but I have to respectfully disagree with scott. Sometimes you can do things right and end up with short end of the stick.
For instance, take Stacey Koon and the other LAPD officers involved with the Rodney King affair. I'm not trying to rehash the case but one thing that was affirmed in both trials is that they acted IN ACCORDANCE WITH THEIR TRAINING. Now, that training may have been for **** but that wasn't their fault.
Anyway, scott is correct in that if you do things the right way all the time, you have much less to worry about than those who fly by the seat of their pants. :D
