Joe:  By your definition of "discrimination", there are many commonly accepted restrictions that will have to be abolished: prohibitions against drunk driving, prohibitions preventing people under 16 from driving a car, medical exams for pilots.  This list goes on and on.  These are all examples of restrictions based on the notion that people need to show that they are capable of operating the device in question and that society has a reasonable assurance that the person will continue to be able to do so because lives are at risk.

You state that they can save lives in the right hands.  Other police officers, can you provide any statistics that support this contention?
