The Ongoing Battle Between To Have Guns Or Not To Have

The shooting of young children and teacher in their classroom is beyond horror and makes one think about the human mind and how it can become horribly corrupted.  But what one has to realize is that guns cannot act by themselves...just as knives, bombs and arrows cannot act by themselves.  They need a human agent to trigger them into activity.  If we had better collection of data that could be processed for information about  whether the purchaser of a gun had medical issues or was a previous felon then that would solve the majority of the problem.  Guns can be used to protect oneself and family or it can be used for murder.  The two have to be distinguished and a sane policy arrived at.  Not this knee jerk reaction every time one of these killings happen.
