I hate reading stuff like this. Thankfully, I haven't heard of a theft at this track I race at, but it could happen anytime. I was thinking of that last week actually because I pit by one of the doors, I am gonna move.
I think the track directors should bring this up every day during the pit briefing. I have too much money tied up in my race cars that if something gets stolen, I would quit R/C. If someone takes just one charger, a couple batteries, and one of my cars and radio? That is well over $1000 easily. Not only that, I usually have my cell phone there, my watch, my sirius portable radio, etc...
