Doug, that is a lot of conjecture on your part and its better that journalists, whether liberal or conservative, not get caught up in the kind of assumptions you have presented. There is far too much we don't know that would be needed to support your assertion. If the shooter's aggression was directed at the church, its ministers or someone in the congregation, his leaving the church might have signaled an end to the shootings. Also, we don't know how much ammunition he had left if his intentions were to continue his rampage. Then there is the matter of how effective an untrained individual would be in these circumstances. One of my fears is being caught in the crossfire between a heavily armed shooter and a well intended but questionably prepared citizen. In such a situation, the police would also be confused as to whom to shoot at and that isn't good either. There is a reason officers wear uniforms.
