Here's the skinny.....
In MA, no one can buy, posess, trade for, take delivery of, or otherwise own ammunition without an FID card or LTC. Therefor, the only people that can legally posess any kind of ammunition for a handgun are LTC holders because an FID only lets one purchase or posess rifle and shotgun ammo. In addition, internet sales in the state are illegal as well, one only needs to drive into CT, NH, VT, ME or RI and you can buy it by the truckload.
How then, are the gangbangers in our urban centers in MA managing to kill each other and innocent bystanders if, in fact, the law actually worked?
These laws don't work here, they won't work in California and they won't work anywhere, anytime, anyplace.
BTW, I don't have a problem with gangbangers killing other gangbangers. In fact, I'll buy them the ammo myself!
