Well, this is a story about a guy who used to live in my hood, and was quite famous fo getting into fights often. Anyway I don't know if this story is true, but it reveals an interesting concept... Namley the above said guy was walking around with his girlfriend and was jumped by 3-4 guys (some stories go so far as to say 20 but i kind'a doubt that). What he did was he started to run. He ran in circles, zig-zaged or did whatever intil his pursuors started puffing so hard that they could barley stand not to mention fight. Then, as the gays chasing him were scatterd all around from all the chasing and no longer a tight pack that could help each other out or attack as a group he ran to each and evry one of them and using his kick-boxing skills pounded the hell out of every one of them. Now, this story...It might be just one of those "Hood Legends", but the point is good. Namley, you need to be in great physical shape and have a certain grasp over a certain martial art (nothing fancy, even boxing will sufice). Then, using the above described technique, or any other way try to break the group into idividuals and then....KIAI... The story doesn't tell what happend to the girlfriend. P.S. you are from Denmark right? Where are the immigrants that you are having problems from?
