There used to be tons of stories of elderly men being beaten to death in Florida all the time, usually for the cash in their wallets. Doesn't happen anymore when they started shooting back.
Not sure why you hate elderly people so much. Maybe you are one of the people who likes to beat them to death for a couple of dollars.

And what you've said is completely wrong of course since the number of murders and robberies went up with Castle Doctrine.
My guess is you're either a gun seller or you're a lunatic that is planning a school shooting.
Now... Describe in single words only the good things that come into your mind about... your mother.
