I lived in Arkansas briefly and this doesn't sound out of the ordinary if there were documented injuries and if you have a record. Which, let's face it, you do! I assume this is a "Battery A 3rd," right?
I think the other guy Quincy was right to make sure you got another opinion, but you say you've talked to two lawyers and an assistant, so I'd just do it.
There's no way in hell you should be allowed to do the time in the First Offender Pod as - think about it - it really isn't fair to the real first timers. Sorry about the "Robust" thing those are no fun. The prosecution is probably jabbing you because you lied, or at least conveniently forgot, about your past. But at least in some jails they let you transfer back to general pop if you keep your nose clean there for awhile, and it is still better than a felony perjury case. Be safe in there and good luck.
