‘Blue Bloods’ Spin-Off Officially Casts a ‘CSI’ Legend for Season 2

CBS has a long tradition of popular procedural TV shows, dating back to classic series like The FBI and Hawaii Five-O. One of the newest additions to that fraternity is Boston Blue, which made its first bow on the network last year. Now, the show is adding a cast member from a CBS procedural from days of yore for a multi-episode arc.
