does anyone know the guy that plays jj's staff sergeant's (the guy that got shot in the finale but is not dead)name or what else he has acted in? i think he's in in charge of the untouchables. please help. it's driving me crazy!!

This is the IMDB profile for the actor that is listed as playing Staff Sgt. Finch...however American Dreams isnt listed on it....there are a couple other websites that do have American Dreams listed on his profile...I can get those for you if you would like. Other than that...this is a pretty good summary of the things he has done in the past. Hope this helps!!

Thanks so much Abby. I knew I had seen him before but couldn't remember where.
