I did a story on this case a long time ago for a local paper, I did a lot of research on it. If I remember 5 witnesses saw “Mumia” aka Wesley Cook kill PO Faulkner including a taxi driver who saw the whole thing from start to finish all of whom testified. “Mumia” also never denied killing Faulkner who he shot in the face point blank. I think the conclusion I came to was “Mumia” was getting all this support from the left not because the left demanded a “fair trial” which “Mumia” got, but simply because of racism by these leftists and I see it’s still going on today.
At the same time, an old talk show host in Philadelphia, the late Irv Homer (who was no liberal) often said he thought Mumia was innocent and in fact Mumia was his news guy in the 1970s. Go figya.
