Your lawyers are telling you that you're going to be convicted, and are explaining why. I know you don't want to hear it. For reasons both rational and irrational. But you should listen. Really. Getting a new lawyer every time you hear something you don't like won't solve the problem, and eventually the district court will stop the lawyer roulette and start the trial.
You're sad. I understand that. You don't want to do a decade in prison. I get that as well. In spades.
But listen to your lawyer. Seriously. Listen. Otherwise your decade in prison will become two decades.
