How likely is is.....? (SPOILERS)
1.) That these 4 homosexual/bisexual pedophiles would end up all working at the same institution, and conveniently work the same shift? (Ritual child abusers, despite how often they appear in the news, are not really that common when you consider the entire population. Plus, there are fewer homosexuals/bisexuals than straights in general, so that makes it even more of a stretch.)
2.) That you could count on one of them to immediately crack under pressure on the stand, and confess everything? (The movie keeps telling us how "brilliant" Brad Pitt's master plan is, but it seems to be built on a lot of luck.)
3.) That 2 experienced criminals/killers wouldn't wait outside a restaurant for their prey to leave, and kill him there...rather than open fire inside a restaurant where people know them?
