If the murder charge is dismissed would the bail be automatically readjusted.? If not what would be required?
If the murder charge is dismissed, and nothing is provided to replace it, there will be no pending charge, and Zimmerman is free.
If the state substitutes a manslaughter charge for the murder charge, the bail remains the same. The amount of bail is marginally predicated on the seriousness of the offense; and is more predicated on Zimmerman being a flight risk, as far as the court is concerned, in combination with a financial disincentive that assures he won't flee. The size of the financial disincentive is supposed to be tied to the defendant's wealth and means of income.
