Let me recast his thoughts in a different manner then. The left forced the released of many thousands of disturbed patients on to the streets through deinstutionalization. The left assures that parents cannot get access to the medical records of their children in college even if they pay for the students education as well as severe restrictions on what the school knows about minor children in lower grades. The left assures widespread gun free victim zones. The leftist MSM provides lurid continuing coverage of shootings when it suites their playbook and advances a gun control agenda. Would all of that increase the chances of more mass shootings?
This was a wildly popular program with support from right (which wanted to save money) as well as left (which had seen One Flew Over the Cuckoo's Nest too many times and believed it was society which was really crazy).
R Reagan was one of the leaders.
