Other things that stood out were:
The morning after story ..either he was lying or the recipient of the murder truck was. Timelines dont match, apparently BW was in 2 places at once! GW4s answer to that 1? His cousin was mistaken.
When they were talking about GW4s multiple sks's, Canepa asked if there were any stored at the FW and he said words to the effect of no IT was not. Lil slip there imo.
On a wire tap GW4 said to JW "you should have destroyed the laptop". This was apparently b4 GW4 new JW was guilty. ALARM BELLS! Why/how would he say that if he had no idea?
He also lied about the time he went to bed.
Just these few points and the fact that he was sparring with Canepa and sidestepping every single question that pertained to the actual murders showed me hes, if nothing else, lying. Why is he lying about something hes not involved in. Why is he lying when his mother and brother are apparently trying to frame him? Complicity was proved to me BARD.
When did he ask for the transcript? Are you talking earlier on in the trial? Canepa asked him twice if he needed to refer to it on cross.
