Stealing is wrong. Especially stealing from me.
Ah, the summer is almost here. It is the season for taking the top off my Jeep. It is the season for absent-mindedly leaving expensive possessions in my car and having them immediately stolen by dirty, dirty thieves. I've had more stuff ganked over the past 6 or so years than I have ever owned at any given time. So, now I register all my prized possessions at juststolen.net. It's a site by law enforcement officers designed to help people recover stolen goods. Of course, it requires law enforcement agencies to use it extensively for it to help out in a significant way. I'm not sure if that's really the case, but at bare minimum, storing identifiable information about your expensive property is a good idea should anything ever happen. From my experience, the more you can put into the police report the better.
