Authorities seek gunman who opened fire at South Carolina church, killing 9

Sheriff: Man kicks in church side door, points shotgun

If you don't want to right click on the links to read the stories here's the gist. In one church a nutjob with a gun comes in and kills unarmed nine people. In the other church armed parishioners stop the armed nutjob before he can hurt anyone. No one dies including the nutjob. You might say that is the exception rather than the rule. Explain these other examples then.
