The ratings-hungry producers/exploiters of “reality” TV are in an ongoing search for “edgy” people who are combustibly watchable and whose lust for fame overrides any sense of moral judgment. Then they act shocked when their “characters” self-destruct. The latest Exhibit A: the suicide by hanging of Russell Armstrong, the husband of one of Bravo’s “Real Housewives of Beverly Hills.” His death came just weeks before Bravo planned to begin airing its second season, in which he would be ridiculed before millions. Sadly, this isn't the first time.
