This has been the case since I've been reading about citizens and guns for half a century or more.
The media would have you believe that guns in the hands of average citizens have never been successfully used for self defense. They love to print/air stories of little children killed by guns their parents left lying around. Or the lunatic who kills people at work with his guns.
So the average person is led to believe that guns are never used for legitimate self defense. It would help if GOP pols would say things publicly about the use of guns by average citizens to prevent or stop crimes from happening.
