This is one of those arguments that ties into common sense being butt fucked into oblivion.
For an example, the "need for interrogation of enemy combatants".
A justification given is that "they know where the weapons of mass destruction are hiding."
First of all, to go back into the main topic, that ties into what I said above:
Rogue states, shadowy cabals, and all that hoopla, do not NEED our science.
What I mean is, these people who are accused of "being in the conspiracy", in point of fact, could make whatever tech they need, ON THEIR OWN, given time, tennacity, and budget. Budget itself comes in MANY forms.
I find it patently ridiculous that people assume the earth is flat and a conspiracy is in effect, by that sheer fact alone. Einsteins work is not a secret. The Russians built their myriad war machines using it. Tesla and his work is no longer in his head. "Genie out of the bottle" kids.
That argument is thus moot.
