of course you can find a single example of a car robbery that isn't trivial.
Where did I say anything about it being someones fault? Of course in a perfect world there would be no theft but aggressive enforcement against car thefts isn't something I support in the real world.
It's also completely unenforceable. Pro theives use tools and you would think the guy owned the car if you saw someone properly break into a car, as there would be nothing to see. Can't have cops ask everyone to turn over their license and title for inspection for walking out of a car with a gym bag.
