Did you miss the posts on dead cops who under extreme stress couldn't even remember which gun they had in their hand and died? Far worse is a HIDDEN "gun jammer" stuck in the chamber of the home defense gun 3 months ago. Under extreme stress, it WILL be forgotten, and result in a jammed gun in the face of extreme danger and get more folks killed than it saves.
More people have died by accidental shooting than died in Vietnam!
Crap. Half of those "accidents" were suicides made to look like accidents for insurance purposes. Many of them resulted from careless handling of loaded weapons which this gun jammer will not prevent. This HIDDEN gun jammer will kill more folks than it saves. Then their survivors will sue "Mike Worley, Inventor of the Safety Bullet".
Smart ones, dumb ones, old and young alike. You can't cure dumb with a HIDDEN gun jammer.
Yes, I was thinking the same thing. He's going to need a 'LLoyds of London' size product liability insurance policy.
