I'm not trading anything! They're not spyplanes. And again, if you accuse every technology that COULD possibly be used that way of being not worth it, then we'd have to take down all the satellites, airplanes, and the cops can't use helicopters anymore.
This isn't black helicopters we're talking about. They can't really see through your ceiling. The only debate is whether it's safe for the FAA to give them clearance to fly around all the OTHER STUFF THAT'S UP THERE THAT'S NOT SPYING ON YOU.
I hear they can't see anything within a 20 foot vicinity of large amounts of tinfoil. Maybe that'll help.
