Good job,Mcrae,You were very brave. I wouldn't have intervened,despite having trained in karate and fighting for years.These days you don't know whether the offender is carrying a weapon or not, or numbed from drugs.But I believe I would have helped you if I was there,but would not have made the first move.Sad to say I don't use public transport anymore,bcos of the crazies around. Don't fence your experience in,talk to someone about it.
