Cooter,
That's what RSA (prime number) encryption if for. Go pick yourself up a copy of PGP for email, no one, and I mean NO ONE knows how to break RSA encryption.
Now I'm sure some guy here's going to come back with "but, the NSA, who knows what they might be able to do, they could break it". Perhaps they could, but they've never admitted it in the past, and for them to spill the beans about their ability to break RSA, it would have to be A BIG DEAL. We're talking top level national security threat, not your typical correspondance.
As far as the original argument... I see what you guys are saying. I almost agree, in many respects, I could consider a mid teens capacity mag for a pistol a "standard" capacity mag. HOWEVER, I still feel that I'm entitled to own a "HIGH capacity" mag, whatever it is that might be. It still seems to me that to ask for standard caps back is to give up on having high cap mags. The worst case scenario would be the anti gunners agree, give you back your 'standard" cap mags, but take away the high caps, whatever those are eventually agreed upon to be. The drums for the AK and ARs would almost certainly be considered high capacity, right? Even in the total abscence of any gun restrictions, a *reasonable* person would tell you that the great thing about the Beta-C mag is it's high capacity, right?!? It's all a slippery slope, and we've learned this lesson the hard way, time after time. You give the antis an inch, they walk all over you. You have to take the extreme stand now, there can be no compromise.
I agree that the "cop killer" label is an anti manufactured term and is complete BS. However, the term "armor piercing" is not... it is just descriptive. We need to have the guts to defend the possession of armor piercing ammuntion, and when somebody asks why, you simply say, "So I can defeat armor, what else would I need it for?"
