Well, problem is, I do seem to recall that an expert witness for the prosecution admitted during testimony that Chauvin did NOT have his knee on Floyd's neck the whole time. In fact, I believe he testified the video indicates that, for the most part, Chauvin had his knee on Floyd's shoulder blades, while he was holding him down.
