ALLI said:why kick them when they are down? what if people see you doing this and they assume you're attacking him (which you are)
if you have to pre-empt or use force for defence then do what is necessary to enable you to get distance between yourself and the attacker, then get out of there. simple as.
I would kick them while they were down for the following reasons
1)because they would have started it
And
2)It would make sure they stay down and give me a little be more time to run
