Really? I thought a lot of those shows went out of their way to show white criminals, especially the ones focused on profilers. On Criminal Minds it seems like it's usually some creepy Ted Bundy looking guy they're after. I mean I can see how crime shows back in the day were probably portraying black and Hispanic people more stereotypically. Just seems like an outdated reaction to what's actually on TV now, as if they studied shows that were popular like 10 or more years ago.
Personally I wish crime shows would feature interracial gangs like you'd always see Bronson fighting in those Death Wish movies. I like how 80s movies made an effort to showcase diverse bands of criminals, and the victims of those crimes were usually a diverse lot, especially in Death Wish 3, the greatest movie ever in the history of movies. Even if you look at Dirty Harry movies, often considered fascist, reactionary artifacts, more often he's chasing white criminals. In 1 and 3 he has to deal with crazy white hippie types, in 2 he actually has to deal with rogue police officers who are acting as vigilantes, and in 4 he has to deal with small town white hick types. In 5 it's some white serial killer dude. And usually his partners were people of color. It's usually that way in stuff like Lethal Weapon and Die Hard too, often some eastern European villain types (DIPLOMATIC IMMUNITY!!! It's Just been revoked!!) For that matter, most of Walker Texas Ranger's villains tended to be white dudes too. Poorly acted white dudes who couldn't handle roundhouse kicks.
