I remember chac posting something exactly like this.
chac can't beat anyone up though, so, it isn't the exact same thing. In any case, scour around any nearby barns and find yourself a lee enfield. Does the job quite nicely.
Or, you can always call the cops again and have them arrest the faggots. Doesn't matter if they know your name, just get restraining orders against them. They won't do anything to you.
