5. The Loose-Cannon Cop Who Looks Like He's From The 20s - Prisoners
So you need a hair style from an era where the line between cops and gangsters was blurred at best - where (or when) do you go? That's right: the 20s. This is a time where you could really rough people up for no reason and no one would give a second glance. The benefits of this haircut lie in the ability it has to come completely undone the instant you move too vigorously (see first image), making you look even more of a psycho when you hit someone who's tied to a chair than you already would have done. This lid screams "don't piss me off", and allows you to run your hands back through your hair to put everything back in place after you've successfully giving someone a good hiding - a sort of "job done" gesture. If I say so myself, Jake really rocks this one; so much so that if you type "Jake Gyllenhaal Prisoners" into Google images, the first related searches that come up are "hair" and "haircut". The public has spoken.
