Fourth Amendment protections good for security.

Quickly,

• John Perry Barlow had contraband when searched for explosives.
• The Fourth Amendment says so what? If all you're looking for is explosives, that's all you get to find.
• Seth Schoen writes about the hearing In the Superior Court of California, County of San Mateo.

Seth draws an analogy to doctors. Doctors learn of illegal drug use but are required not to reveal that to police. If patients are afraid of the police, it makes it harder for the doctor to do a good job.

Likewise, if innocuous travelers are afraid of the police, they are induced to behave suspiciously (hiding things), which distracts screeners from real threats that also behave suspiciously. We're less secure as a result.

And, oh yeah, it's unconstitutional.
