Given what has been alleged, the guy should be hanged. As for looking amongst ourselves; I am not going to do it. I am not going to question others' decisions whether to own or not and whether to carry or not. If they decide to use a gun as a tool for their malevolence, then they should be held accountable for their actions, not the implement they used to carry them out.
...I also am unafraid to be held by these same standards.
