... not as defendant, but as a juror.
I served on a jury last summer for a case of armed home invasion. The victim, if you can call him that, was a multiply-convicted white crack user. The victim claimed the defendant forced his way into the defendant's house with a gun, as part of a dispute over the defendant's missing cell phone following a drug deal.
The defense attorney's goal was to convince us that there was no way to determine beyond a reasonable doubt whether the defendant committed the crime, or his brother. The police did a horribly sloppy job of gathering evidence, the DNA was so contaminated that while it matched the victim, it also had good odds of matching the defendant's brother or about 1 in 5 random people off the street. The victim lied on the stand several times and showed no reliability as an eyewitness, and all the other evidence (phone calls, evidence collected at defendant's house) pointed to *some* member of the defendant's family, but no way to know who.
So we found him not guilty. Kind of a shame since the defendant probably *was* a drug dealer, but no way to prove it wasn't his brother. And the kicker: if they bring the brother to trial, he can use the same defense.
Doubt is not a pleasant condition, but certainty is absurd. - Voltaire
