No point dwelling on it. Won't do you any good. Instead focus on bringing back mental institutions and involuntary commitment. Until these folks quit being told they are normal and anyone who disagrees is not it will continue. Untill something is done about the poor folks who are homeless talking to their imaginary friends are cared for, until the kid who is showing the world his intent and daydreams of murder and torture, it will keep happening.
I've been saying this since one of the first mass shootings at a school happened at Colombine in Colorado back in 2000. We didn't have this problem when the people who couldn't cope with society were living in state hospitals. And wouldn't have this problem today if those people were still living in state hospitals. It's the truth and anyone that's old enough to remember the days prior to Colombine know it's the truth. I'm not saying that there wasn't an occasional incident when someone went "postal" or some jealous husband went to the workplace of his wife's lover or things like that. But mass shootings at schools and churches just didn't happen.
There is a need for state hospitals. The mentality ill should not be left running loose in society and trusted to take their meds and function like a normal human being does from day to day. It just doesn't happen that way
I'm sure I will probably get flammed, but oh well. There are plenty on here that know it's true.
You may want to read some criminal history, prior to 1980. Stuff like this has happened, all over the world, for hundreds of years, different scenarios, different child predators. They are most often housed now, in state and federal prisons, paid for by the taxpayers. There are more than a couple corrections officers and ex/ current LEO on here that can confirm that.
The difference now, is that we currently have a 24/7 news feed, reporting, no matter how accurate, their opinion of the event.
