I have had two broken noses, as anyone who has seen my profile would know. Both bled profusely - but the WORST bleeding I have ever had or seen on anyone else is a scalp wound. The scalp has an amazing blood supply, and as far as I know it will invariably bleed like nothing else when cut. That is why pro wrestlers make a tiny cut in their forehead or hairline so they can have their face be a mask of blood in a fight. It is not really dangerous and does not even hurt that badly - but the blood pours.

Zimmerman claims a scalp injury from having his head smashed into the sidewalk. THAT would bleed like crazy. And there is no sign of that.
