In the real world, incompetence is a more likely explanation than some intricate conspiracy.
A few points about Michael Baden. He was chief medical examiner (not coroner) of New York City for one year before being fired 40 years ago. He is now 85. I don’t want to sound ageist here but there comes a point for everyone to surrender the stage to younger talents. Leaving that aside, is he really an expert on the specific topic in question, i.e. has he published a recent, large prospective study on pathological findings in suicidal hanging?
