The amount Zimmerman raised WAS IN THE NEWSPAPERS! How can the prosecution argue they didn’t know?
They knew and that is what upset them -- the amount of grassroot support he has. O'Mara said that the $150,000 bond was already quite high for a case like this. So knowing about it at the hearing shouldn't have raised the bond any further.
Usually a request for revocation of bond is because the defendant is a flight risk -- but O'Mara already had the passport and PayPal money in his possession from as far back as April -- and the prosecution knew it because they had been notified.
This d&p show yesterday was done to attack GZ's credibility. Clearly, even though he will probably not take the witness stand in his defense, they are trying to challenge the credibility of the statements that he gave to the police which will play a large part in the trial. Unfortunately for the prosecution his statements are corroborated by witness statements and forensic evidence which they can't make go away.
