Yeah, saw this at the weekend and is very sad. As said above, just let them take it, not worth loosing your life over - it can be replaced, but I agree with what Tom said, it just makes me angry that these low life's can just walk in and take what they want. Fortunately, my house is pretty secure, they're not getting in when it's all locked up (anti burst front door and windows see to that! - the Police hate them as they can't use the battering ram and you can't force the locks or hinges).
It's just madness really. If they did get in, I have a lovely air gun waiting for some point blank shots - anyone having done airsoft will know how much that hurts!
