Liability
Locked Account.
I have seen cases where the criminal case hinged totally on a medical opinion of doctors. The doctors come and testify before the grand jury and one of the doctors' testimony was not exactly what the prosecution believed it would be! It was totally opposite of what the other 2 doctors had testified to.
So which doctor is "lying"?
Perjury is rarely, if ever, indicted and prosecuted. In almost every trial I have seen someone will take the stand, swear to tell the truth "so help me God", sit down and then violate that oath.
Real world is not like TV drama.
A difference of medical opinion is not the same thing as lying, necessarily.
