Talk about the downside of biometrics

Apparently these thieves have been watching Alias one to many times. On a side note this week on Alias they scooped out a dead guys eye for use on the biometric scanner. I had to look away.
Cars can be replaced. Fingers cant. Really makes you wonder about the wisdom of these biometric scanners.

Police in Malaysia are hunting for members of a violent gang who chopped off a car owner’s finger to get round the vehicle’s hi-tech security system.
The car, a Mercedes S-class, was protected by a fingerprint recognition system.
