It's strange how the question of guns and mental health have somehow gotten muddled together in this string and in the public mind. I doubt that the shooter who opens fire in a school or other crowded "gun free" place is mentally ill in the sense of having a treatable mental illness. Sociopaths or psychopaths (I'm not sure of the distinction between the two terms) have personality disorders that may not be treatable, so the situation in Seattle, Portland, etc., may not be in any way comparable to the ones involved in the mass murders. Not being a shrink, I'm really not qualified to say much more.
Great video on Seattle, Kathy. Interesting how the mentally ill are still smart enough to go where they think they can get a lot of free stuff, and the politicians of Seattle have gone out of their way to accomodate them, to the detriment of the voters, who seem good at wringing their hands and deploring the situation, but act helpless and unable to vote those idiots out and replace them with some grownups. It's going to take some "brutal" action to restore sanity to that kind of situation.
