BINGO! So many folks want to depend so heavily on a certain caliber
Is it .45ACP? I'll say this, I don't depend on .45ACP, nor do I think any more than a couple oddballs depend on it, but I can have it, so I do. I think an AE.50 is a bit much, but wont knock somebody for wanting it or using it for carry. (EDIT: also in the case of 21 hits, a tiny bit extra each hit adds up if you can't get a good shot. Every little bit helps IMO)
As mentioned before, my first thought was WTF were they thinking, but then after reading it sounds like I wouldn't have yelled "POLICE" either. If you shoot at ANYONE - I don't feel they are obligated to state who they are, or to demand that you stop. They said some were in plain clothes as though they makes the police the bad guys here, but what about the ones that were in uniform? It should be pretty safe to bet that when you're commiting violent crimes in public that the police will show up within a few minutes. Just a shame they couldn't have gotten one good shot it, I suppose it's got to REALLY suck being shot 21 times. Pehaps he will realize the error of his ways and the great pain he has caused others, and now himself.
