I've been very lucky, grew up in rural area's, lived Ina couple of small towns and Bristol while at school, moved to Exeter for a couple of years, then joined the army... So inside a secure fence, patrolled by armed guards, and theft is unheard of, for simple reason everyone knows everyone. While in single accommodation stuff would wonder if not chained down! But would be mainly military kit and again all pretty minor. Then the military put me in a civilian house, in Birmingham... Handsworth Wood, I have been assured 20 years ago it was. Nice area, but stopping at a red light could end up in your car being stolen (probably why nobody stops at red lights). Then moved to edgbaston, supposed to be a much nicer are... But not that much better. Many thefts, every house has CCTV, alarm systems, double dead lock front doors, security lights and so on! The guy opposite has been burgled three times in four years and the only thing he does not have is armed guards!
It's sad that we have to use these measures!
