Isn't this an offense? Can't they be sued for lying to the public? Why do they get to get away with this?

It's easy to tell the public you're invading privacy to prevent terrorism. It's hard to tell the public that terrorists killed people because you respected their privacy.

I'm not saying I agree - in fact I completely disagree - but as a public policy maker and politician, it probably seems illogical to do it any other way. Better to have people blame you for no privacy than blame you for death, right?

Also, there are campaign donations to be had from the vendors of full body scanners. Less so from civil liberty groups.

It seems extraordinarily unlikely to me that campaign donations from millimeter wave vendors will exert anything resembling the force that game theory does; to wit, "voting yes to anything that might improve airport security, and avoiding at all costs voting no on something that might later be tied to some catastrophe".

I think kickbacks is a more likely motivation here.
