1. How in the name of all that is holy or even merely sensible is a heavy, hard-recoiling and (probably) wrong size out of the box double-barreled shot gun "easier to use" than a lightweight, highly-adjustable, low-recoil AR-15 in .223? Are you really that ignorant?
2. How in the name of -- well, the name of Anything At All -- does it make sense to randomly discharge a shotgun when under threat? Especially if one takes your full advice to "fire two blasts" from a double-barreled shotgun and is then left holding a heavy, awkward club? --You really are that ignorant, aren't you?
3. Please pass this along to Mrs. Biden: Look, you're living at the Naval Observatory. It's a well-secured site. If somebody's lurking or trying to break in, lock yourself in the bathroom and call Secret Service or the Navy; they are mere seconds away. Take the shotgun along but don't fire it unless you have to. Stay the hell off the balconies; maybe you dote on ol' Joe but he doesn't know what he's talking about when it comes to self-defense.
Gah. Vice-President Joe Biden: in favor of unaimed gunfire, ill-fitting guns and home-defense hardware better suited to "Green Acres" reruns than real life.
