A threesome is what you call five black guys having an orgy.
What do you mean by 5 black guys being a threesome?
I mean that blacks are over-represented in crime statistics.
The statistics you're looking at may represent specific black communities and not the general population overall. You could be wrong about your deduction that black people are more prone to being criminals.
What are your sources? I like statistics.
There are many sources to cite crime stats in specific places as well as more general ones.
