Posting bail in the local case is not going to get him out of jail. He will simply be picked up by the other jurisdiciton and held in their jail on the bench warrants, and I would expect the bonds on the bench warrants to be prohibitively high. Additionally, as soon as you post bond for him he won't get out of jail due to the bench warrants and he will stop accumulating credit on the local case. Therefore, you would be doing him no favor and actually hurting his accumulating jail credit on the local case. You should at the minimum wait until the bench warrant situation is straightened out before considering posting bond for him on the new charge. Right now he it sounds like he needs an attorney more than anything else.
