Civil liability
Cars and guns are registered so they can be traced. Wrenches are not, nor are hammers, knives, and crow bars. Furthermore you are responsible for cars and guns until you no longer own (sold it)or control them (stolen). There is not only the question of crime, but civil liability. Defending either of them will cost big bucks for lawyers, and your homeowners' probably will not cover you. Furthermore, you can never predict what a jury will do. Be easy on yourself, get a bill of sale signed by both parties.
