IMNSHO---and not bashing the OP messenger--- He did not shoot himself at a 'Gun Show'--- he suffered the consequences of a negligent discharge, perpetrated upon 'hisonself', by negligently failing to clear and secure his own firearm, in a Parking Lot adjacent to the premises where the legal sale/purchase of firearms was being conducted. Glock/schmock, .22RF, .520 Loudenboomer--- #1= Firearms Safety Rules RULE!
I DO have compassion and sympathy for him for the consequences of his negligence, for it very well may happen to me one day, if I'm equally negligent.
Could Have happened in his own driveway/ residence, and Would Have, if he had been Negligent in the same fashion. "Gun Show" arena is ONLY media fodder for the Anti's. In his driveway, would go unnoticed by the Media.
Argumentative Supposition-- had he not been required to unload/ reload his firearm, might this incident have been averted outside the 'gunshow' ?? Yep--and occurred as easily maybe later in a mall/daycare/countryclub parking lot w/ more disastrous consequences.
#1-- Gun Safety must be followed, ALL Ways, at ALL Times-- None of Us are immune from the consequences of not doing so--but We already know that. Easy to slip up-- reminder to Self--- DON"T slip up!
Let's be careful out there.
