I had my camera bad swiped in Peru while shooting a doc. I had State Farm and they were great. Full coverage. But that was mentioned in the thread.
Since I've traveled and filmed quite a bit, I think this is a good bit of advice in general. I actually bought a small cable lock, the kind you lock a bike with. Now, whenever I'm on location, I always use the cable lock and attach my Lowepro backpack to something, that way, it's much harder for someone to just walk up while you're working and swipe your bag.
For example, if you are traveling in Europe and have your regular clothing backpack and your camera backpack, while waiting for the train of whatever, tether your camera and regular backpack together with the cable lock, then you're that much safer. Takes about 30 seconds to do.
If I had done that in Peru, I would probably still have my kit.
