Ahem.
"Black Gangster Disciples, Vice Lords, and Sipp Mob gangs". That's three entitites.
It's right there in the OP.
Moreover, "black" modifies "gangster" which modifies the noun, which is "disciples".
The point remains -- their races were not identified. The OP made it up.
Just as the last bullshit artist did. He got busted too.
'Black' modifies 'people'. Or, sort of 'people'. Maybe animals.
You're reaching in order to excuse the obvious. Dishonest.
I'm reading the English language. I even know how it works. You should try it.
The inconvenient fact remains whatever the first entity means, two other entities follow it.
The other inconvenient fact remains, the article never identified the 17 as "black". The OP made that up.
I said that before, as long as two months ago, but some o' y'all remain dedicatedly dense.
