To me, there lies the biggest problem! If you kill an intruder, who can blame you right? Wrong, they will be more than happy to charge you with illegal usage/posession of a firearm.
It happened in Winnetka a few years ago. A man broke into a house and took everything. A few months later, he returned and the homeowner was home.The homeownershot him and he was charged!
Now, because of the way this new lawcan be interpreted,we will have the same thing happening with most shotguns and rifles.
