“To those who seek to avoid action by their National Government in their own communities; who want to and who seek to maintain purely local control over elections, the answer is simple:
Open your polling places to all your people.
Allow men and women to register and vote whatever the color of their skin.
Extend the rights of citizenship to every citizen of this land.”
President Johnson, March 15, 1965

“But the right of free speech does not carry with it, as has been said, the right to holler fire in a crowded theater. We must preserve the right to free assembly, but free assembly does not carry with it the right to block public thoroughfares to traffic.”
