The strategy of introducing last minute motions and subpoenas to delay the state and attempting to poke holes in the warrant is sound. If none of that pans out he can always just take a plea deal.
FWIW, he's doing all the right things, and just hoping that he can catch a break. It's unlikely he will though and he'll take a plea. No way he takes this to trial, I mean, Nick is retarded but not that retarded.
I hope I'm wrong though, at least on the last part. Him taking this to a jury trial would be incredibly entertaining.
