It could be like the trial of the policemen who beat up Rodney King. If the first jury doesn’t produce the right verdict, they can always try the defendants again on some other charge until they get the right verdict.
And this I believe.
Way back in the day, I read about the trial of the policemen in the Rodney King incident. The prosecutor made a huge blunder right from the beginning. He charged the cops with something like "attempted murder", which under no circumstances would the evidence support, and of course the Jury had no choice but to find them "not guilty."
Had he charged them with some supportable lesser offense, he could have likely gotten a conviction.
I see the same circumstances playing out in this case. They are going to over charge them, and the evidence will not support the allegations against them.
And you are likely right. The Feds might step in and flip the verdict using their special "double jeopardy" trial.
