Bias, reputation, and motive are irrelevant to the claim that "Epstein suffered multiple fractures in his neck that are more consistent with strangulation than suicide by hanging". 1) Did Epstein suffer these fractures? 2) Does established forensic science support that these fractures are more consistent with strangulation? 3) How much more? 4) Is there other evidence that supports the conclusion this was suicide?
The pathologists uses facts and established scientific knowledge to draw a conclusion. Legitimate responses to that conclusion should be factual and scientific. Counter arguments along the lines of the "middle class people don't understand the justice system" or "this guy was paid", however true they may be, don't have any bearing on the neck fractures and if those fractures are consistent with strangulation or suicide.
