If that happens, they would be large riots probably making the King Assisination Riots dwarf in comparison, the factions in the CRM that want to work through the Federal Government would be discredited because of this castrated bill, probably leading to several urban insurrections, that probably leads to a 60s PATRIOT ACT to save the country. Oh shit this is during the beginning of Vietnam, if so I don't see the US doing well in the 70s or 80s.
Either successful revolution or naked fascism in the cards honestly.
