MSNBC has a chirpy piece about all the wonderful technology that's slated to take the place of common sense and good gun handling.
Of course, all the gadgets and gizmos in the world won't keep a dumbass from shooting himself in the foot, as long as he's the dumbass with the key to the internal lock and the fingerprint reader recognizes him as an authorized dumbass.
Gun safety begins with education and ends with good habits, rigorously and constantly practiced. All this Rube Goldberg garbage dangling off guns these days makes them safe only in the same way welding the barrel shut would; by making them useless. Which is what the other side views as the endgame, anyway.
