If George is not freed from jail this would hurt his chance at a fair trial. When you are in prison during trial, jury can have a more negative view of you, not to mention that he does not deserve to be in jail.
A person that saw himself being railroaded in the future, might just want to have a exit strategy, I can understand that! Sure it`s not the case here, but something I might have considered
You're right, but it's not because the jury has a more negative view--in fact, most times, jurors won't know if a defendant is being held without bail. He'll show up in court in a suit and he'll look like he would if he were out.
The real problem is that when he's in prison, he can't help prepare his defense like he otherwise would. His lawyers are going to be working a lot of hours in the days leading up to the trial, and he would be with them a lot of that time if he were out. In jail, it makes things a lot more difficult.
He'll obtain bail. He's entitled to it unless the court finds one of three things - the state's case is airtight; Zimmerman is a dnager to society; or Zimmerman is a flight risk. If the judge does not make one of those findings, then he must grant bail that defendant can afford.
