I had four of the local scumbags sent to prison after they gave me an absolute pasting (they were taking running kicks at my head). Before the trial I was receiving death threats and my home was coincidentally burgled three times.
I have given first aid to a stranger who had been punched to the ground during a mass drunken brawl as the fight went on around me. I was perfectly sober. The guy died a few days later and I had to appear at court as a witness.
I see the first one as braver as the second one was just a snap reaction.
