State v. DNA profile

By Gideon

In these days of DNA, scientific and forensic evidence, it was bound to happen. As this very interesting (and lengthy) opinion from the California Supreme Court details, a “John Doe” warrant issued mere days before the statute of limitations was set to expire, identifying the defendant only by his DNA profile, satisfies the “particularity” requirement of the Fourth Amendment.

The DNA was taken from a crime scene (and victim) in 1994 and after the issuance of the warrant, a cold hit matched the profile to that of the defendant. Only problem is, the DNA taken from the defendant was in violation of then-existing CA law.

The defendant raised several challenges to the warrant: that since the DNA was taken in violation of the law, it was in violation of the 4th Amendment; that this triggered the exclusionary rule; and that the warrant was not specific enough because it was issued in the name of “John Doe”.

You can image the usual responses to such claims. The court relies on the abomination that is Virginia v. Moore to dispense with the first argument: that just because state law prohibits something, doesn’t mean it is a violation of the Fourth Amendment. The second is dealt with by regurgitating the very narrow reading of the exclusionary rule (and the third argument was just plain silly to begin with).

This shouldn’t be a problem anymore for most states, since the statute of limitations for all sex crimes is now one googol years (an actual number). But the case is a curious oddity nonetheless and it is my solemn sworn duty to bring this to your attention.
