I have a background in martial arts, but if you hit some random person in the head, you could kill them. It's a really bad idea all around. You don't know what kind of medical issues they have.

If you have to, hit them in the gut, a good punch there will end things very quickly. If you know how to put your weight behind it and you're decently strong they'll crumple like paper no matter how big they are. Pretty safe, too.
