DNA Evidence Exposes Our Shoddy Legal System

For a great description of how the DNA evidence that's turned up over the years has revealed the shoddy nature of our legal system, check out this excellent article by Ed Brayton. It's as far from a scientific enterprise as we could get, particularly when it comes to eyewitness IDs. One commenter did have a noteworthy recommendation:

"I was able to give a very good description of the assailant, even though I said I couldn't ID him. Rather than concentrate on his face, I concentrated on getting a good look at his clothes - particularly the pants and shoes (they're harder to change), and comparing his height and weight to mine. It actually ended up being better information to ID the eventual suspect, who was caught and convicted."

This advice (the part about the pants and shoes) works better when the perp is on the run and the police are looking for him /that very day/, but it wouldn't work when it comes to looking at a criminal line-up, where the perp is probably not wearing the same clothes. The part about noticing the size of the criminal was good advice.

Concerning DNA and the legal system -- Brayton raises some good points.
