i think all the commentators I've heard [so far] are missing the point on Malaysia airline shootdown
What it means is that a small band of terrorists only has to get their hands on one of these weapons... and they will no longer have to try to board airliners. Wait to see what happens to ticket prices when your ticket when the TSA is rendered instantly obsolete, and we begin paying instead for military-grade anti-missile countermeasures.
(prediction: this point is not lost on the CIA, and now that the NSA is reading this unencrypted submittal, they know it now, too.)
