I casually left my car unlocked and intruders searched the night. They only took the registration and insurance card (Ohio, USA). It seems strange to me, because these things are not really useful to anyone except for the personal information they contain, although I do not think it's enough information to support online accounts or to make me to pass for a person. Strangely, they did not take low-stakes items like change, or high-value items like a dashboard camera and expensive sunglasses, or even plates, that would have been helpful with the recording.
What should I worry about as a result of this leak of information?
