Here in AZ, and I am sure in most states, spitting is considered an assault. If your assaulted you can defend yourself. And considering the possibility of someone spitting on you that has Aids, I would consider it aggravated assault.
Paintball would be my choice too.
I've only gotten the finger once so far.. Most of the comments have been good. But AZ is not the most "Liberal Friendly" state in the Union..
