I'm not seeing how that hampers the defense.
If his attorney is worried about GW4 getting the DP, why not just contact the prosecution and arrange for a plea deal with LWOP?
Most suspects in multiple murder cases where the prosecution has all the evidence they need don't usually get such a good deal. What's wrong with not taking risks and settling for LWOP?
what's wrong with going to trial if you continue to state you are innocent, we know the evidence, they know the evidence, but BW and GW are presumed innocent until proven guilty, or they plead guilty, and why would they settle for LWOP when they have one last roll of the dice a trial,
and I think the defence is hampered by the fact that if they get JW to change his story, or add to his story by a good cross examination then they have made the DP viable for all 4, if they don't do a good cross examination of JW then they are also not doing their job, either way the state having the power over whether the DP is reinstated hinders the defence
they either chose to go after JW thus placing their clients penalty back as possible DP or they go easy on JW which means them not doing their job, which is to vigorously defend their client
we shall see how it all plays out at trial, we also have yet to learn what the judge rules on the outstanding motions that have been filed,
