IMO the legal stoush between Brennan and Alessi misses the most significant development here and it's a big difference for trial 1*
It appears that the CW does indeed now have the timestamp for the start of the key cycle with the high speed reverse. If so, any theories about it happening after seizure of the Lexus are out.
Much more of Alessi's cross of Whiffin/Hyde makes sense now because it seems he was setting up to argue that despite that high speed reverse, it happened a few seconds before John locks his phone. So it can't be manslaughter/murder.
It's a clever technical argument in isolation, and of course it could work, but it would mean all of the defendant's BITS version is false.
Could a jury really believe Karen reversed at 24 mph clean past John who is standing to the side, the Lexus hits 'something' and then meanwhile John locks his phone, takes his final steps and is murdered or suffers misadventure seconds later?
Even if there is variance, a timestamped high speed event seems a very bad fact.
And what to make of AJs statement in opening that they both got out? Was that a misstatement or do they have the drivers door opening?
* I am always a bit hesitant to read the tea leaves of motions as they are not evidence, but it does seem that both Alessi and Brennan accept the time stamps and are arguing about a 30 second variance in time line.
The above is speculation by me, based on tea-leaf reading from arguments by Brennan and Alessi
Brennan's statements about the timestamp "ignition on and off" 7 hours 8 mins approx
