It's largely due to "da culture". What's glamorized and put on a pedestal in "da culture ".
A few hours ago extremely popular rappers Ice Spice & Nicki Minaj dropped a colab where they repeated proudly "I fell in love with a gangsta":
That's all these kids hear these days.
That's who the kids worship these days.....the gangbangers, drugdealers, street dudes etc.
"Da culture" has been manipulated to influence as many young black males as possible to think being a gangsta is "cool".
The prison industrial complex depends on this.
