The Eighth Amendment to the U.S. Constitution guarantees the right to reasonable bail. There may be an Arkansas law or provision in the state constitution about the right to bail. The only defendants held without bail are those charged with serious crimes who are a significant flight risk. I don't remember what you told me your offense was, but I remember it wasn't a serious crime. If you surrender, you've got the flight risk test covered. So unless the courts in Arkansas are like those in 'Midnight Express,' I think you'll be granted bail.
I think you should man up and surrender with a lawyer. "A coward dies a thousand deaths, a brave man dies but one."
