Are you not afraid of a bad guy with a gun because you know the idiot is not likely trained in how to use it ? That would make  sense.  The Idiot  is not going to hit you from any distance greater then point blank.
As opposed to a trained gun owner that could take out a dog trying to attack his child.
BTW I'd much rather read a story about a dead dog then a 3 year old kid having it's face tore up by the some dog.
