1. You want to shoot up the school or a movie theater: you are the registered owner of the smart gun, so there is no problem.
2. You want to rob a liquor store: you are going to use a Saturday night special that is not registered to anyone, so there is no problem.
3. You want to defend yourself from the intruder in your home who just killed your husband: the smart gun is registered to your dead husband and it will not fire for you, so there is a problem.
Happy Day of the Dead
