There's really nothing you can do. You can try to negotiate with them, but you will most likely run into bureaucratic red tape. I am not aware of a waiver for indigency, or a hardship waiver for this situation.
Possibly. There are going to be several timing issues involved in this matter. You should speak with a local attorney to see what can be done to avoid jail time in the DUI case, and how to avoid a possible probation revocation.
Hire an attorney to help you with this charge. If you are convicted of the DUI Georgia law requires a license suspension, and 12 months of probation. If you can get the charge reduced to something other than a DUI then you can avoid the license suspension, and 12 months of probation. Your fine may be able to be paid out of your bond if you posted cash, and you posted it yourself in your name.
You also need to worry about the effect this can have on your license because each endangering a child count, counts as another DUI offense for purposes of determining how long your license will be suspended for. For instance, a first offense DUI conviction carries a 12 month suspension, but you can get your license back after 120 days. The same DUI conviction with a conviction for child endangerment is treated by DDS as a second DUI conviction in a 5 year period which carries a 12 month...
When everything comes back negative the case against you should be dismissed. You need to make sure all of the charges are dismissed so you can expunge the arrest. Don't plea to any of the underlying traffic violations, if there are any, because this will stop your chances of expungement. You cannot sue because the police enjoy sovereign immunity in most situations, and this would most likely be one of them.,
