Apparently so, as I have been schooled on this thread.
Well, it's a stereotype.
When most people think of "serial killer" they think of the high-IQ Ted Bundy who terrorized the nation while murdering college girls.
In reality, most serial killers are low-IQ blacks who randomly stab prostitutes and homeless bums. Not Hollywood-worthy.
Just like when people think of mass shooters, they think of angry white guys with manifestos and social media profiles who shoot up a school full of people with promising futures.
Again, most mass-shooters are blacks who shoot up their own in acts of rage at a block party or a corner dice game. Again, not Hollywood-worthy.
