The medical examiner & I got into a bit of correspondence. Actually, he did NOT know anything about pharmacology, or even anything about the details of the analytical chemistry. He just trusted the lab blindly. People with fancy titles do not necessarily know anything. Ultimately, the data wins the day, not the fancy title. And quite frankly, you have to be skeptical of anyone working for the government. Their job is not truth and clarity. Their job is helping the police to convict. They are a sausage factory.
