Effective security vs "security theatre"

Bruce Schneier says the measures implemented at airport security gates aren't making us any safer; they're just for show. [Link]

But only temporarily. Banning box cutters since 9/11, or taking off our shoes since Richard Reid, has not made us any safer. And a long-term prohibition against liquid carry-on items won't make us safer, either. It's not just that there are ways around the rules, it's that focusing on tactics is a losing proposition.

It's easy to defend against what terrorists planned last time, but it's shortsighted. If we spend billions fielding liquid-analysis machines in airports and the terrorists use solid explosives, we've wasted our money. If they target shopping malls, we've wasted our money. Focusing on tactics simply forces the terrorists to make a minor modification in their plans. There are too many targets -- stadiums, schools, theaters, churches, the long line of densely packed people in front of airport security -- and too many ways to kill people.

Security measures that attempt to guess correctly don't work, because invariably we will guess wrong. It's not security, it's security theater: measures designed to make us feel safer but not actually safer.
