I've never seen it confirmed, but it strikes me as pretty obvious that the TV franchise "Law & Order," which debuted in 1990, was heavily influenced by Tom Wolfe's 1987 bestselling novel Bonfire of the Vanities. Wolfe's novel is about NYC detectives and prosecutors, bored and depressed by arresting and convicting countless poor minorities, hunting down for fun and political profit The Great White Defendant, rich white guy Sherman McCoy. "Law & Order" is the irony-free version of Bonfire, with the first half hour consisting of detectives arresting a rich white person and the second half hour consisting of the prosecutors torturing the law to come up with some absurd justification for charging the defendant with homicide. This formula has made L&O perhaps the biggest franchise in television history.

It might be an interesting factoid for an article that there are more white murderers plotted on Law & Order (all editions) than there are actual white murderers in New York City.
There were 572 murders in New York City last year. We know that only 10% of violent crimes in NYC were committed by non-Hispanic whites, so if the same is true for homicides in particular, that's 57 white murders. There are three "Law and Orders," I think, with about 25 episodes per season with, say, 80% being white. That's 60 white New York murderers on one set of shows compared to about 57 in all of the real world New York.
Anyway, I bet it's close.
