Weasel Zippers alerts us to a story from Alabama where a female heard a knock on her door. The person knocking claimed his car had broken down and was needing assistance. He forced his way in and was armed with a knife. The home owner was armed with a gun. WSFA 12 has the details.
Here is another case of someone using violence to enter the home. I highly doubt the reason for the knife was to make a peanut butter sandwich. Had the homeowner not been armed, the intruder probably would not be the one dead.
