Two cases so far this week in the Tulsa area where guns carried by citizens made "the difference". One a home owner who found a stranger standing beside one of his children's bedroom door in the night. The stranger ran when confronted.
The other a case of a pitbull ( dog ) who was attacking two women. In the last case the man shot the pitbull when it turned on him when he arrived to help the women who were being attacked. Bet there are more cases that I have not heard about.
P.S. The woman who owned the dog would have been better served with a gun when she needed help. She could not help the two women when her dog attacked them.
