“Blood follows gravity, so if the entry point is behind the head, it won’t be going against gravity.”

The entry point from where the snipers were stationed would have been in the front of the head. The entry point with a high power rifle bleeds less than the exit wound. The expansion of a bullet blows out the exit. The size of the exit wound depends on the type/design of the bullet.

All that taken into consideration a head wound bleeds profusely, and if the bullet actually exited out the back of the head it should have created a path of spray. However, with the angle the shooter was lying on the roof the bullet could have traveled down into the body, and bullets don't always track a straight line after impact.

EDIT NOTE: I don't know what type bullet the snipers were using, but I think it safe to say when you might be required to shoot into a crowd you don't want bullets that pass straight through to kill innocents. I think it likely they were using some type of hollow point or ballistic tip that would retard penetration.
