The people on the far left want to ban guns and the people on the far right want to prohibit the mentally ill from owning guns or have the ability to drive a car legally. This is what somebody posted on a gun forum as their proposed legislation for gun control: I can see it happening. Three years from now, a person with any history of mental illness will not be allowed to own guns or drive a car. There will be a national data base for the mentally ill just like there is for convicted felons and sex offenders. Doctors will be very reluctant to certify a person who has undergone psychiatric treatment for a mental illness as being healthy enough to own a gun or drive a car for fear of being the target of civil litigation. Once you're determined by a doctor to be mentally ill, you'll be taking the bus for the rest of your life. Now the question being: What's going to be the official government definition of mental illness?
