that's not even the evidence you need.
All you need to look at is the rate of exonerations, while on death row, when new forms of evidence become standardized (E.g, DNA), old forms have been exposed for the shoddy quakery that they are (fiber matching, bullet scoring, much of arson investigation is a shitpile), oh and of course the reality that nature of human memory casts incredible doubt on witness testimony. We know these things, and we know it has exonerated dozens.
So, just looking at the rate of modern exonerations, imagine how many have been executed, long long ago for the same fake bullshit evidence. There is no denying it. Also through in the generation of that white myth of the "evil black predator!" that saw so many being sent to the chair for simply finding enough "proper witnesses" to condemn a man for just not looking right. This is our history. No one is inventing this.
