Yea, Yea... Kirkland was a good choice for RJ, and so is first CBI chief, Minelli (sp?), but I truly think that RJ is best suited for a split personality serial killer type dude like Rigsby. I personally think that it would be cool, very cool. 
I understand that McAlister was played by a good actor, an actor I consider one of my favs, but the sheriff just didn't work for me, and I think for a lot of other peeps. Most of us are even wondering if Gotham will be dropped on its ass in similar fashion, I mean... who hires the Fresh Prince's wife for a criminal anyways??? Seriously?
Also, Bertrand was a good choice, a bit to old school, but at least he would have made a good character because of the direct influence over CBI agents. AND, let us not forget the Head Cheese of Visualize. One cannot go wrong with Brett Stiles/Caligula as a serial killer. 
Soooo many possibilities, so many other viable options left out to the elements, and we are left with cowboy boot wearing, sheriff McAlister, WTF?
I just want to say, this new jack-booted FBI circle jerk is boring and depressing. Witches says that the last episode is named "white tulips", well I know where Heller can plant his white two lips. Im fucking depressed... Why not make Cho, the literary "chinaman", RJ, and send my over a cliff?
