Greg Houser Portland, Ore. As a U.S. citizen with lifelong major depression, I found this article about Donna’s Law, which allows individuals to cede their Second Amendment rights to purchase firearms, to be both condescending and invalid. This is a mental-health-treatment issue, not a gun-control issue. This is an issue of real horror faced by intelligent people who reach the end of their ability to endure another minute of mental torture. We need mental-health outreach, advanced treatments, more money for psychiatric-drug research and understanding. Those of us with mental illness aren’t drunken drivers who refuse to give up our car keys. We aren’t “Clint Eastwood types” at a gun range, laden with automatic rifles. But thanks for the extra stigma. Sue McCraven Williamsburg, Mich. For goodness’ sake, we allow compulsive gamblers to ban themselves from casinos. Why haven’t all 50 states already passed a version of Donna’s Law? Or better yet, why isn’t this a federal law? Steve Klouda Sugar Grove, Ill.
