Yesterday, my wife and I were coming back on the regional train from Karlsruhe when a group of 4 drunken high school students (ages 16 - 18) boarded the train at one of the stops. They were speaking very loud and acting aggressively so I went to code yellow immediately. Then, as we approached one of the train's stops, an old lady stood up from her seat and walked towards the exit, since it was her stop, but it was precisely where the young lads were located. They began insulting her very offensively, pushing her around, mocking her and would not let her reach the exit of the train. She was obviously very affected, screaming and crying. I was shocked that no one went to her aid. I then went to code orange and started debating whether to interfere. Then as soon as the train's doors opened, the men started pushing the old lady violently and they pushed her very strongly through the doors and the lady landed face first on the train ramp. That's when I knew I had seen enough. Mind that I am 30 years old, 6'2", 225 pounds and a brown belt in Kyokushin Karate. I was also carrying a Spyderco UK Pen Knife and Sabre Red pepper spray.
Anyhow, I stood up and told the boys in German to get off the train immediately before I called the cops. They laughed and one of the boys approached me in an aggressive manner, so I proceeded to spray him in the face with a 2 second burst of pepper spray in the face. He went down holding his face and screaming. Therefore, the other three boys ran towards me. I then sprayed a second boy on the face with another burst and pushed the other through the doors of the train. The other stood there scared and then just exited the train. Two police officers rushed towards the train and took the boys away and another police officer was already attending the old lady's abrasions in her face. I have to admit, even though I acted properly to defend an innocent victim, I was scared that the German Police would find some excuse to charge me and arrest me since the gun laws here are ridiculous. Well, I was shocked when the police officer shook my hand and told me "Danke Schön Herren!" which means "Thank you Gentleman" and then a few passengers clapped their hands in gratitude.
Ok I know that I exposed myself by confronting four attackers without a handgun or at least a baton, but I just felt that I had to do something to help that lady and teach those boys a lesson. A good old saying just kept circling in my head: "It only takes for good people to do nothing, for evail to prevail."
Anyways, just wanted to share my self-defense experience here in Germany.
