Not sure if you want to read any more of this stuff on McCammon but it got published today, so thought might as well highlight yet another article... http://bornoffside.net/2012/08/mark-mccammon-and-the-gillingham-race-case/? Probably the last one I'll do, until any appeal.
Quite well written I think. Also shows they have looked at all evidence available and not just jumped on the racial bandwagon like so many others.
There was one point that was wrong in the article - which didn't state that McCammon was playing to the best of his ability !
