If you're 14 like you claim how are you showing up on scene in a car with a license plate that says "firefighter"? You can't drive yet.
I'll only echo the comments made by others here and go one further by saying perhaps if EMS moved away from the volunteer model and stopped giving away services for free (and thereby devaluing the industry as a whole) then we wouldn't have to worry about silly things like badges. As it stands EMS has larger things to worry about than wearing badges. Education, for example, is something to worry about.
