a gang?!? strikes to the adams apple and strikes to a certain "special" spot at the side of the neck, i've been in karate most of my life andi'm pretty sure even if everything went perfectly, and i was even able to tough out broken bones and keep fighting (if i knew my life was in danger mabe a 5% chance) i'd only be able to take 4-5, only because if i get the first strikes and they hit the target (i'd have to surprise them) i'd be able to take down 4 (theoretically) before they could do anything, of course if one thing went wrong and i missed, i'd be completely defensless and get my face ground into the side of the road). if your talking more than 4-5 people you could have a switchblade and a suit of armor you'd still lose.
