TV shows today don't make gang violence a subject
Still, that's not the only problem with TV today: even leftism has poisoned the atmosphere for a long time now, to the point of where you might not be able to do something that's favorable for the US army, in contrast to TV series of yesteryear, which had some. For example, when Mission: Impossible was produced during 1966-73, there was an episode where the team investigated a commie-run filming studio that was crafting phony news footage showing US soldiers committing atrocities in Vietnam; one of the earliest series that used 'Nam as a subject, and was favorable to the US army. And if you want an example of a series that alluded to anti-white sentiments, in Renegade (1992-97), there was an episode that may have been in 2 parts where, while Reno Raines was escaping from a prison with a bunch of black convicts, they threatened him at one point with a knife and addressed him as "white boy", before he was able to convince them that the leader they'd left behind was dying of a disease and not in a way they'd previously assumed. Today, you could not expect to find anything this inspiring, given how politically charged the atmosphere's become.
But whether or not any of these ideas can come to light sooner or later, Lott may be right that gangs, even black and Hispanic ones, can make for a story on TV, and writers shouldn't let political correctness get the better of them, not even the networks and syndication corps.
