Thx.
One other thought - if Nifong loses his job, whomever comes into the job after he vacates is going to fire Wilson, most likely. The new DA will want to purge the organization of any stink lingering from the case, and that would of course include Wilson big time.
Wilson no doubt realizes this and thus understands that his and Nifong's fates are entwined, so look for Wilson to cover for Nifong as best he can.
