To be honest, and I know people won't like this but I am entitled to voice my opinion, but I feel you deserve it. Anyone who keeps their backup right beside the original data is asking for trouble, especially when you swan off for half an hour leaving everthing out in the open and on display in an unfamiliar environment. What the hell were you thinking? I bet the thief couldn't believe his luck nor that someone would be so stupid.
It wasn't the best idea to have everything in one place, but to say that he deserves it is just ridiculous.
