Unowme, you asked a question earlier about hole carding and why someone would thing differently about that. Was that directed at me because it wasn't clear who you were asking.
Mission: prosecutors chose not to prosecute and drop charges everyday. It NEVER means there was no crime. It means the are not confident they can make their case and get a conviction.
This being a new kind of case the feds probably made some mistakes that lead to some of the pre-trial motions going against them which weakened their chance of winning. The Feds jumped in and took over this case. That was probably a bad move. They should have let the state's go first and if the same mistakes and pretrial ruling went against them, the Feds could have had a second crack. (Which wouldn,t be double jeopardy). But jumping in they had only one chance and when mistakes were made and pretrial motions went against them....they were done.
