i heard a rumor his morning that the silva guy recently had a really bad medical diagnosis
no excuse for what he did though....
I'm not a mental health specialist, but whether or not that rumor is true, it demonstrates an important point.
No matter how many background checks, mental health evaluations, invasive medial records checks or in-person psychological evaluations the state mandates, it's never going to solve the problem.
Someone can pass the tests 100%, then suffer a head injury, traumatic event such as bad breakup, divorce, death of a relative/s or especially a child, develop an addiction to prescription or illegal drugs, fall in with some bad "element", become addicted to gambling, lose their job and house, receive a devastating medical diagnosis, etc, etc.
These events can cause someone to 'snap', and there is no way to prevent it. Sometimes is a compilation of events over time until the weight of it becomes overwhelming.
The same things that cause suicides can also cause a 'need' to harm others as well. Sometimes it's a means to an end if they are unable to kill themselves. They commit crimes in the hopes someone else will end them.
Trying to isolate, identify and "society-proof" people with these problems is an impossible task. That's why the mentally ill were institutionalized for decades until the 1980s. Now it's a question of who pays for the institutions and whether the mentally ill have the same rights as the rest.
I guess the gun grabbers never saw the movie
The Village. No matter how hard you try to control the population, it's just not possible. Human behavior is going to always include violence because of mental illness or a lack of moral/social conscience. There's no way around it.
