Good Samaritans...a story in question.?

As a police officer and first responder I am protected under a good samaritan law. I cannot be sued as long as I stay within my boundaries. This basically means that as long as I don't do anything outside of my training I cannot be sued. Obviously if I try to do something I have not been trained for and that person is injured more because of it they can sue me. This is how it should be everywhere and should be this way also for any citizen who just tries to help without administering first aid beyond what the average person should know and understand!
