So now, at worst, negligent homicide is a “FEDERAL” crime? Did you get your law degree from the same place you attained your dual masters in biology and physics? I’d ask for a refund.
Convenient that you ignore the part where i said “NOW PUT A GUN IN HIS HAND”.
You ignore the FACT an assailant just might be faster/stronger/a better fighter than the Mighty BoomerSquid(delusions of grandeur much?).
You ignore the FACT that it might not even be you in the fight, but your wife/daughter/mother(though I’m sure they’re all super marksmen/cage fighting/ninja bad asses, right?).
You ignore the REAL possibility of more than 1 assailant(but they always come at you single file like a Bruce Lee movie, right?).
And THIS(I said edged/blunt weapon, not knife, didn’t I?) is going to cause a bit more than a few “superficial” wounds to your feet or ankles.

By the way, good luck NOT shooting yourself in one of your flailing legs while trying to deflect a weapon with your feet, but I hear femoral arteries are like appendixes, not really all that important.
Alas, all of this is moot. Early in this thread I challenged you to point to a SINGLE agency that authorizes “frangible” rounds for patrol officers. You HAVEN’T, and you WONT, because you CAN’T. Instead, you all but made the grand declaration that the universe alters the very fabric of ballistics and human anatomy when a badge is pinned on the shooter. You’ve all but claimed on high that said badge, somehow, allows officers to ignore missed rounds.
You wont(because you can’t) present one stitch of EVIDENCE to back up your claims about the EFFECTIVENESS of “frangible” handgun ammo, aside from how “nasty” that shallow wound will look.
You wont(because you can’t) present any EVIDENCE that handgun rounds, and “frangible” ones in particular, are more EFFECTIVE “fight stoppers” than .223/5.56.
You wont(because you can’t) argue my POINT that a long gun is inherently more ACCURATE, FASTER on target, EASIER to retain and EASIER to shoot.
You wont, simply because you can’t. Instead, through your frustration and failed attempts to deflect FACTS, you sling insults and rhetoric. When faced with FACTS you don’t like, you change the question. When other fail to simply fall in line, you make a base appeal to “YOUR AUTHORITAH!!!”.
