Yes, just as if their car is used in a crime.
Obviously if someone breaks into your house, breaks open your gun safe, takes your gun, goes down the street and robs a bank with it, that is not your fault.
But if you leave a loaded gun laying around unsecured, and a four year old grabs it and shoots a five year old dead, you, the gun owner, have just committed homicide.
Almost everything else is in between, and yes, there is a line there, or more than one, that has to be found. But we are a civil society and we can deal with the difficulties of drawing that line. And, anyone who is uncomfortable with there being such a law can easily address their anxiety. Just live in a gun free home.
I bring this up because the Washington Post has a new piece by John Cox and Steven Rich addressing this issue. Here.
And, right, if your car is locked up and in your garage and the key is with you in the house, and someone breaks into your garage, hot wires your car, drives down the street and uses the car in the commission of a crime, that is not on you. If, on the other hand, you leave your car unlocked and running on the street and somebody jumps in it and takes off and commits a crime with the car, that is at least partly on you. And somewhere in between lies this line, see?
