Yes and ok this makes me think again, but I wouldn't say I'm an armchair hero, it's just that my stupid side is go head in first and think later....so probably not a good way to be. I went and broke up a fight outside a friends house one morning at about 5am, and these guys were having a proposer fist fight. And truth be know, I should probably not have waded in, but I did, and the police came, but like I said, I'm stupid and should know better.
I used to live right next door to a post office in Twickenham and one night some guys were robbing the place, and I went out with my baseball bat, and frightened off the lookout, when the police chased them by coming they my house and jumping over the wall, the policeman said he would need to interview me but told me to out the baseball bat away and it would not be mentioned in his report.
