I carry concealed for the same reason. It was actually a pit bull attacking my lab puppy at a dog park - for no reason - that finally pushed me to go ahead and get my ccw.
That will not happen again. I will not allow it. If it is attempted, the offending pit bull will learn what its like to get shot 10 times as I empty the magazine into it.
Amen
Right now, here in my state, there's at least one guy doing time, a long time, because he fired three times when twice was enough.
