The MSP uniform is trademarked. The troopers you see in the movies are troopers in "real life" (if they are wearing the correct uniform). So, too with "Spencer for Hire": Troopers Spellacy and Richardson appeared in that program. Obviously, Kevin Bacon was CPAC (or FudgePac, as it is known in the troops), as he wasn't required to wear a uniform. I thought I recognized a couple of former "B Troopers" on the bridge...
