There's (predominantly white) armed right wing militia literally walking the streets of US cities. It's not exactly a new thing but still, the absolute state of these lads.Yeah, because white people never pose with weapons or take drugs.
The way I look at drug and gun culture in black America is this: Black Americans tried to create their own economy, legitimately and within the bounds of society and the law. They did very well in places like Tulsa, and then white people destroyed it. They literally rained fire down from the sky and burned it to the ground. And even since then, black people have been marginalised and disadvantaged. Law enforcement has not helped them and has been complicit over the years in destruction of property, beatings and lynchings.
So they've built their own economy outside of the state and have their own means of protecting it. If they're outside of the state then they have necessarily to deal in things the state does not control, black market stuff, drugs, strip clubs and the like. And if they distrust law enforcement, and they are operating an economy which is outside the protection of the law, then they need to protect it themselves which, in a country like the US, means being armed. Even someone like Killer Mike, who is a legit businessman and activist and was pleading with rioters in Atl to go home, is a vociferous advocate for black people arming themselves because he simply doesn't trust in the protection of law enforcement.
The drug and gun culture, such as it is, didn't just spring up from nowhere.
