Short answer is yes. If I made the decision to loan my car to someone and they intentionally committed a crime with it, I think I should be investigated for my involvement. If it turns out I had no reason to suspect this was going on, cool. If it turns out this was a problem waiting to happen, then I’m responsible for my role in it.

Now the hammer is a bit of a mess, because it is not difficult to acquire a hammer so you would have a hard time saying the crime couldn’t have been committed if not for my specific hammer.
