"We've been told we have to trade off security and privacy so often -- in debates on security versus privacy, writing contests, polls, reasoned essays and political rhetoric -- that most of us don't even question the fundamental dichotomy.
But it's a false one.
Security and privacy are not opposite ends of a seesaw; you don't have to accept less of one to get more of the other. Think of a door lock, a burglar alarm and a tall fence. Think of guns, anti-counterfeiting measures on currency and that dumb liquid ban at airports. Security affects privacy only when it's based on identity, and there are limitations to that sort of approach.
Since 9/11, approximately three things have potentially improved airline security: reinforcing the cockpit doors, passengers realizing they have to fight back, and -- possibly -- sky marshals. Everything else -- all the security measures that affect privacy -- is just security theater and a waste of effort.
By the same token, many of the anti-privacy "security" measures we're seeing -- national ID cards, warrantless eavesdropping, massive data mining, and so on -- do little to improve, and in some cases harm, security. And government claims of their success are either wrong, or against fake threats.
The debate isn't security versus privacy. It's liberty versus control...
If you set up the false dichotomy, of course people will choose security over privacy -- especially if you scare them first. But it's still a false dichotomy. There is no security without privacy. And liberty requires both security and privacy. The famous quote attributed to Benjamin Franklin reads: "Those who would give up essential liberty to purchase a little temporary safety, deserve neither liberty nor safety." It's also true that those who would give up privacy for security are likely to end up with neither."
