Doucette is an idiot, but I understand why he's an icon for them. Aside from being idiots themselves, until Shane got the one vaguely smart idea he's ever had and selectively released a tiny portion of the TDMA letter to rope in "lawtwitter" with what looked like an easy to mock case or more likely Casey did and had their dancing monkey enact the plan, all that kickvic had were Canadian paralegals and 'my uncle is a judge', which Nick demolished without even trying. When Doucette rode in, bald head shining like a lantern of hope in the darkness, their BS legal strategies finally had a 'lawyer' (and then a bunch of other hangers on) to spout the same garbage in more legalese terms. Now they could shout down anyone on Vic's side who wasn't Nick, and because they insisted even before that Nick was a bad lawyer, they could also just disregard him with 'nyeh nyeh, our lawyers are real, unlike you'.
It's still stupid, and their lawyers are still as useful to them as an anonymous canadian paralegal and a fake UK magistrate, but now they can pretend that Nick lazily batting at them like a bored cat with an old ratty ball of yarn is him getting dunked on and put in his place. I imagine that's partly why Nick's stopped inviting any of them to his show. When they first arrived he treated them as equals and thought they just needed to be informed on the situation so they could give their own perspective on the case. Now he knows either through stubborn myopia or sheer incompetence, their opinion on the case has as much worth as an imaginary judge.
