we have to go back to Reagan and his decision to rid the country of State and Gov run mental institutions. Yes, they were in bad shape but to eliminate them completely and hope that something would miraculously appear to fill the gap for the mentally ill was foolish.

The HCR bill actually has a provision to deal with Mental Health in this country and we need to talk about how it will benefit communities.
