It appears that Ziegler is seriously disturbed - just one example is his obsession with OJ (had plan to kill him). I don't understand why he is taken seriously and put on national television. I guess it's the illusion that there are "two sides" to everything, no matter how nutty one of the "sides" is...
"...Winter '95: During his sportscast, Mr. Z. makes "an incredibly tame joke about O.J. Simpson's lack of innocence" w/r/t his wife's murder, which draws some protest from Raleigh's black community. John Ziegler is eventually fired from WLFL because the station "caved in to Political Correctness." The whole nasty incident marks the start of (a) Mr. Z.'s deep, complex hatred for all things PC, and (b) "my history with O.J." He falls into a deep funk, decides to give up sports broadcasting, "pretty much gave up on life, actually." Mr. Z. spends his days watching the O.J. Simpson trial on cable television, often sitting through repeat broadcasts of the coverage late at night; and when O.J. is finally acquitted, "I was nearly suicidal." Two psychiatrist golf buddies talk him into going on antidepressants, but much of the time O.J. is still all Mr. Ziegler can think and talk about. "It got so bad—you'll find this funny—at one point I was so depressed that it was my goal, assuming that he'd be acquitted and that Riviera Country Club wouldn't have the guts to kick him out, that I was going to become a caddy at Riviera, knock him off, and see whether or not could get me off on jury nullification. That's how obsessed I was.""
