The one thing we are overlooking in all of these mass shootings. One four letter word.

17. Rage is not a mental illness

It can be a valid feeling. Anger, even extreme anger is a very ordinary, common response people have when they believe that they have been treated unfairly. A fantasy about killing the guy who fired them, the banker who denied a loan, or bullies at school does not even necessarily reflect a psychiatric illness. It's clearly unhealthy, but does not necessarily reflect a diagnosis of a mental illness. Particularly in a culture that embraces vengeance. If it is difficult to act on their fleeting fantasies, they are less likely to. Along with ready acceptance of vengeance wink wink "reasonable fear" as a reason to kill people, the larger problem is easy access to what can make the fantasy come true quickly and with little physical effort.
Whatever happened to waiting periods? Why not waiting periods, mandatory training and thorough background checks required by federal law? Why not conferring some legal penalties for irresponsible gun handling. For example, giving a teenager who has not met background check and training requirements. Maybe some of these people who are irresponsible that their toddlers get a hold of their guns should be prosecuted?

I can only question and speculate, but I really think an explicit goal of making it more difficult to kill oneself or other people should be a consideration.
