I been thinking about this after watching the 60s: The Decade That Made America on CNN. How much effect did the Civil Rights Movement on LCN political connections?
It seems, according to most mob historians, that it had a negative affect on the LCN's political power. Perhaps not so much the civil rights movement in and of itself, but it being part of a larger movement for more open government and reform, which did away with much of the old political machines and institutional corruption in many cities.
