I don't worry very much about this case affecting gun laws. Much greater atrocities have occurred (i.e. Columbine, VA Tech) with negligible after affects on the gun laws. This case will grab peoples' attention for awhile, and then it will be eclipsed by the next thing in the news cycle and will be forgotten. Except of course by the families of the parties involved.
"Is this gonna be a stand-up fight sir? Or just another bug hunt?"
