Testing someone's pulse- with your THUMB??
Surely most people know that you have a pulse in your thumb, and should never check your own/someone else's pulse (ie. the carotid artery in their neck) with it?
From Medical News Today-
"Finding your pulse on your neck (carotid artery)
You can find your pulse by pressing two fingers on the side of your neck (carotid artery), beside your Adam's apple in the hollow area."
Even the dumbest medical rookie would know this, or any civvie with an ounce of brains, yet CIA analyst Ryan - whose wife is a doctor- performed this classic film mistake upon one of his dead colleagues at the ambush - thumb to neck! So the dead guy might have seemed to be alive.
Just more Hollywood retardedness.
