When Tom and Jimmy respond to the car accident, Jimmy shocks one of the victims with a defibrillator but doesn't press the "shock" buttons on the paddles.
In the scene where they're taking a boy who was in critical condition to the hospital. Tom is in the back with the boy and Jimmy is driving. In real life situations, Jimmy who is a Paramedic should have been in the back, being it was a Advance Life Support situation. Tom who is a E.M.T-Basic should have been driving.
Jimmy: I see how it's gonna be now. Some things are okay, some things aren't okay. Gotta run things by you first, see if it passes your little code of fucking ethics. Fuck you.
