With a little bit of logic...
I've been waiting to see if someone else reaches this conclusion. Far as I can tell, they haven't, so it needs to be said. It seems blazingly obvious to me.
Simple syllogism.
TSA's internal stings are able to get weapons and explosives on the plane 95% of the time.
If "terrorists" existed, or more precisely if "terrorists" were actually a serious enemy, the "terrorists" would be making similar tests with non-simulated explosives. Since 95% of those tests would succeed, we'd have a WHOLE FUCKING BUNCH of exploded planes.
We do not have any exploded planes. Not one.
Therefore "terrorists" are not a serious enemy.
We do have a problem with non-"terrorist" moles like Lubitz, a Kraut with no "terrorist" connections. Using only an overblown manic sense of humorless Kraut self-importance, he crashed a plane after carefully going through all the stages to become a certified pilot. We may have a similar event in the Malaysian plane that went down near Australia, but we'll probably never know.
