Careful here. I'm a licensed gun owner and a medicated citizen. But my medications (issued through the VA) aren't mind altering or for psychological issues. They're for heart problems, blood pressure, cholesterol, stroke. But simply saying medicated citizens are the problem is painting with too broad a brush.
Being issued through the VA, my medications ARE part of a government database. Yet I have no problem obtaining my FOID renewals.
There's nothing so permanent or resistent to change as a government database.
I apologise for my broad statement. I should have been more specific about the mind and behavior altering meds, routinely prescribed by shrinks. Maintainance meds like for blood pressure, diabetes etc are not of the mind altering variety.
I would be interested in knowing what kind of prescribed meds the shooter was on. I would suspect ritilin or something of that class.
