My Thoughts on Why there are Mass Shootings in the US

Due to horrible abuses of the past and the cost, states all closed down the long term mental health care facilities in this country except those for the criminally insane which are quasi prisons. The problem is what happens to those who need long term mental health care ??
Most end up homeless on the streets or in jail. Ever wonder why 50+ years ago there were as many guns as now but there were NEVER mass shootings---why ??
Fifty years ago these people (mostly paranoid schizophrenics) were in long term care and were no longer a danger to themselves or others. Look into the history of the shooters and you will see in almost every case someone who has been in and out of mental health facilities and the doctors have said that they are a danger to themselves and others but there is no where to send them for long term care. So they give them drugs and send them on their way. The person stops taking the drugs, becomes psychotic and plans and commits a mass shooting. THAT'S the cause of these things and society is paying the price one way or another.
