Need Help Describing A Person

Did you want a full-written description? I can think of some key words for you to get you going, anyway:

Personality:
Confident/cocky/sure of his abilities
Intimidating
Intelligent
Compassionate (he'd have to be able to do what he does)
Just (for this one, it'd be best incorporated with his temper, and describing just how just he is)
Critical/analytical (also argumentative for the purpose of figuring things out)

Physical Appearance:
Tall
Solid
Big (by this I mean he just appears big all over - kind of like someone's taken a picture of him in Photoshop, stuck a lasso around him and enlarged him, while everything else stays the same.

... And that's all I've got so far. I hope it helps a little!

he's always struck me as autistic. I say this because he rarely ever socializes with anyone and has a number of tics and things that he does when he's talking to suspects and witnesses (like that thing he does when he holds his hands behind his back and bends over) if you saw the episode with the guy with asberger's then you'll see a lot of similarities between him and goren http://en.wikipedia.org/wiki/Probability_(Law_&_Order:_Criminal_Intent_episode)

personality-wise, I'd say he is determined, obsessive, honest, blunt, and controlled

physically, he's got curly black hair, a permanent five-o-clock shadow, and always wears a neat business suit. he's a bit heavyset and very tall. he has an emotionless face most of the time on the show, like he's bored or sleepy.
