re: In your opinion, did OJ kill Brown and Goldman?

I believed, based on the evidence, that he killed them.

What, for me, completely confirmed that belief:

His "That's a lie!" outburst, complete with pointed finger, when a detective testified that the shower drain in his bathroom wasn't damaged during evidence collection.

During presentation of gory evidence and testimony that he did this/that during the murder, he didn't utter a peep, just doodled or joked with his attorneys or looked bored.
