rapper C-Murder's lawyer helped him secretly record album while imprisoned

Is this an ethics violation? Apparently recording music and videos in prison wasn't specifically against the rules of the prison C-Murder is in. Anyway, the Sheriff is pissed off and thinking about reporting the attorney to the bar. I just think the whole story is sort of humurous.
