Hey, if my grandma comes at you unprovoked, by all means defend yourself.
This is not only a Right, but also a Responsibility of all Americans. In defending yourself, you defend all of society.
If Victim #1 shoots the ****** between the running lights, there'll never be a Victim #2.
Unfortunately there are entirely too many sheep in this country who prefer to be taken care of by the government, so they can have an entity to blame other than themselves when something bad does happen.
Only you are ultimately responsible for your safety.
Freedom=Personal Responsibility, take it or loose it.
