In the reality genre, which is built on notoriety, what does it take for a network to shut down production on a series? Pretty much nothing. The dissolution of a marriage in front of million of viewers and eight kids didn’t stop TLC from finding a way to continue “Jon & Kate Plus Eight,” whose latest reincarnation is a series of “Kate Plus Eight” specials. And it was the cops, not A&E, that halted filming on “Steven Seagal: Lawman” on Wednesday following the filing of a sexual harassment and sexual trafficking lawsuit against him. The Jefferson Parish Sheriff’s Office where Seagal is a reserve deputy cited the legal case as a distraction for the department. For the producers, that’s just good TV.
