In a Court of Law, when one might be proscecuted under the "Good Samaritan Law", the evidentiary edict would be "Do nothing more, or less, than what one has been taught". Consequently, to prove the knowledge would be statutory, in the case of a licensed physician. Ironically, a physician can be sued for NOT doing what s(he) has been taught...in other words,
s(he) could be sued if s(he) did NOT volunteer their expertise, in a critical situation, in which they were fully trained. As a matter of evidentiary law, the Good Samaritan Law can only be implemented on a VOLUNTEER basis.....without charging, taking, receiving, any money-in-kind for the effort.
