Possibly. But just because he defended JE doesn't necessarily mean he was privy to all that was going on. Maybe he didn't find out until later what his client/friend was really doing. I think we should wait to see what evidence is being presented. Also, unless I'm mistaken, in the original case it was the prosecution who acted improperly not AD(that we know of)
