It's a cliche on Twitter and in crime reports that a young black man shot while attempting to murder a police officer will turn out to be an "aspiring rapper" even more often than he'll turn out to be an "honor student" or a "gentle giant". (Deceased Ferguson thug Mike Brown was all of the above—sample rap lyrics: "Devil get off my back / I'll knock you off your feet / Another man down in my city") See better (=worse) lyrics here.
Well, my previous post "Allahu Akbar" Gunman Not An Arab, But A Black Guy Who Hates Whites suggested that Fresno gunman Kori Ali Muhammad, 39, is not a part of secret international Muslim plot, but just a random black guy shooting whites. It turns out that he's a genuine aspiring rapper (see video below, with graphic content )which I think confirms it.
