NY Post (alleged to be New Yorks' conservative newspaper!):
"The haul included military-grade machine guns with silencers as large as the weapons themselves and Soviet-era assault rifles with flash and smoke suppressors."
"The arsenal’s most powerful weapons — .45-caliber handguns — “could kill an elephant,” said a law-enforcement source."
"The arms were initially bought for $200 to $300 a pop through two networks — one in South Carolina and the other in North Carolina, states where gun laws are notoriously weak, officials said."
"About three dozen of the weapons had been stolen down South. Most were peddled fully loaded."
Again, I didn't know that stealing guns was legal in the South....
“The arsenal’s most powerful weapons — .45-caliber handguns — “could kill an elephant,” said a law-enforcement source.”
Chortle. An idiot talking about guns.
I would guess if traced nearly all were stolen.
