"Ban guns, and you may, or may not, reduce the death toll from a mentally ill person on a rampage with a firearm. Help the mentally ill, and you WILL reduce the death toll from mentally ill person using a firearm, bomb, arson, automobile, machete, etc."
The illness compels a few to kill, it doesn't compel a specific tool. Heck, James Holmes admitted that he considered different methods - what will the anti's do if/when they ban guns? Shrug their shoulders when a mentally ill person can't buy a gun and instead uses a bomb to kill 168 people (a la Oklahoma City) and say, "well at least he didn't use a gun"...?
Interestingly, there was a Stanford study that found Schizophrenic patients in India hear voices that didn't tell them to kill, but benign suggestions like "clean the house".
So there must be something that can be done about it.
So, I should have provided (much) more context in my original post.
I was somewhat surprised to see those articles, because they show some real *progress* towards identifying (and thence, coping, hopefully) with mental illness. Not perfect measures, but some progress.
I see on the comment boards out there, many anti's say "There will always be crazy people" (...and of course there is a broad spectrum of mental illness out there - and the vast majority who suffer with a mental illness pose no increased risk of harming others)
I don't share that bleak outlook - I think progress can be made, identifying mental illness and making things better - and I'm somewhat surprised that so many anti's just reject that idea, in their eagerness to get their gun ban.
I think showing knowledge of the subject (and even some compassion) and showing that it is (will be) an effective solution, might be good for convincing those on the fence to go the "solve mental illness" route, instead of going down the "gun ban" path...
Something that should also be accounted for in firearms law is the idea that at least some mental illnesses can be transient - the anti's don't give a rip if someone was going through a difficult time in their life and was committed briefly for depression - every person barred for life is a win for them, regardless of circumstances.
Some states do have a process for restoring rights after commitment, but the process is usually expensive and time consuming, as such processes usually are - and in other states, one commitment, regardless of circumstances, or the time elapsed, is a lifetime ban.
Lastly, the criteria for commitment, and even the transparency of the process, is downright scary in some states. I've read some horror stories where people didn't do anything that would get them convicted in a court of law, but did get committed and "poof", there went their rights.
