I'd go with "more than zero".
I wonder why we don't pay these troops enough to get the people we want.
I used to frequent a bar that a lot of firemen hung out in. There was a famous shooting here in Portland a few years ago. As it turned out the police tazered the guy after they shot him dead. The fireman were joking that it was a bet as to whether they could make the corpse release his bowels. I can’t verify that this is what actually happened, but I can say for sure the firemen & EMT’s said it had.
