Wrong... Wrong... Wrong...Dicion,
...To my knowledge you don't have an EMS/RN/MD certification/license that could be suspended or revoked leading to the loss of your employment and/or career. You as a lay person have no duty to render aid to the person who you just hypothetically shot. It is not that simple for someone who holds a license as a medical professional. While the law may not require medical personnel to render aid; the licensing agency may look at things totally differently when it comes to the obligation to fulfill ones duties as a medical professional. It may seem cut and dry for the non medical professionals, "that guy attacked me, why should I help save him?" but it becomes a real grey area when it comes to us medical professionals. Please don't think that I am trying to imply that medical personnel are superior to anyone else, nor am I trying to be disrespectful of your service to our great nation or the training that you received during that service
You have no legal duty to act unless you are ON DUTY and RESPONDING to that scene. That is Roles and Responsibilities 101. If you are off duty and outside of your jurisdiction, you ARE a lay person in the state's eyes.
The aftermath of a defensive shooting is going to be dynamic, to say the least. My immediate concerns.... are there any more bad guys?... am I injured and can I fix me?... are my family/friends injured?...
The ONLY thing I'm going to be thinking about the BG is if he can get up to try to hurt me again.
