If you don't like guns, don't own one. IF you don't like me owning a gun, then find some counseling that will assist you to adapt to reality. The law says I can own as many firearms as I wish. When the stats suggest that more folks are murdered by guns than are saved by guns, then we can have a legitimate discussion not based on the ignorance of non-gun owners.
I don't know that truth about how the school murders took place and the police response, but I will bet you that there were dozens if not all of the police on site that wanted to rush to the rescue. Based on experience, my thought is that they were ordered to stand down and stand by until the "bosses" made a decision. I would like to believe that everyone one of those police would be or are potential heroes but were ordered to hold.
A possible scenario; one or some of the Cops disobeys orders to stand down and rushes into the classroom. He snaps off a shot and kills a child. Think of the repercussions. Second: he rushes in and gets shot and killed. Ok, so that's his job except he was ordered not to rush in. In the first scene, he kills a child and gets fired and charged with manslaughter, subsequently going to jail. The county gets sued, not that it would be the first time a county is sued. But, what protection does a Cop have if he disobeys orders which then results in his making a deadly mistake?
I have seen very few cowardly law enforcement officers, but many heroes. I personally believe they were held in abeyance by orders from their superiors. That's just my opinion.
As a civilian, we do not have the restrictions that officials are held to. Sometimes that works to our advantage, but it can sometimes result in careless actions and harm.
