Well let me end it before it starts...it doesn't make you any better, unless you are not used to shooting at someone while they are leaning. Like everyone says, aim for the mid section. I mean, it's not like you would aim for the head most of the time anyway, because it's the smallest target to hit. Leaning will give you an advantage running around a corner, but a very small one. If you don't have a fast reaction time, you'll still get blasted just as easily.
