Sorry you don't want to hear it, but STUPID, close-minded jury on the O.J. level. They just wanted to get the hell out of there. One of them had a plane to catch, or didn't you hear?
If you can't present a case sufficient to convince even a few of these jurors, either your factual case, your presentation, or both are lacking.
Jurors don't lose cases, lawyers do.
And, second guessing the motives of jurors you know nothing about is beyond stupid.
