Just a couple of comments
First of all, what kind of a wacked out maniac does it take to use a shotgun on another person, especially family members? We all know what a messy and grotesque wound a shotgun makes, and pretty much represents a form of excessive, intentional, "overkill".
Second, it is interesting to know what a wonderful job the NYS pistol permitting system does as far as denying these kinds of wackos permits to carry a pistol. They stated that both had received pistol permits this past September. If the permit system does not detect this kind of mentally deficient applicant, then what good is the system. Yes, it was a shotgun used, and there is no permitting system for long-guns, but my point is that requiring extensive background checks and jumping through hoops to obtain a pistol permit is supposed to weed out the insane. Worked pretty well in this case didn't it?
