Just talked to my dad about this when he came home from work. Don't know if it was mentioned but the brother says the guy (shooter) was autistic. Now normally I would call this BS for someone trying to get out of jail time, but seeing as he shot himself it made me think. Perhaps he belonged in a mental institution. Mental institutions were shut down a while ago, because people see them as unjust and brutal. In some cases they were right, the staff didn't give a crap most of the time and treated the patients like animals.
However, with the removal of these institutions, families are FORCED to deal with their child and in most cases don't know how to.
The shooter was 21 I think? He was above the legal age meaning he can make his own choices to be on medication or not. In mental institutions they keep you on your meds. I think the real problem here is that the family didn't handle the shooters condition correctly and didn't seek help for him. Autistic people are very hard to detour from what they set their minds to. Learned this in psychology. Perhaps he got violent impulses, the family didn't know what to do, the mother tried to stop him and he shot her. Then he went to the school and did the terrible things their.
Again I bring up mental institutions. The US has a history of just tossing aside things that don't work instead of just fixing it. Yes the institutions were brutal and inhumane, but with extra rules and boundaries and powerful punishment, they could have worked out. Instead we have mentally challenged people who are homeless, running the streets and to be honest some of them are dangerous.
Yes this story is sad, but if the killer really was autistic then you can't exactly blame him fully. That sounds terrible, but it is true, their minds work differently. I am saddened by this story, but I hope that it shines light on the fact that maybe these people do need places to stay in which they are monitored and watched over so things like this does not happen.
