Lyndon Johnson actually said...

"Your courage and your self-sacrifice have provided us with a glowing example of what I believe is the best of American manhood."

"And of those who wear the badge, I ask an equal respect both for the law and for the rights of the people they are sworn to protect."

"I ask not blind obedience, but enlightened obedience."

"I ask patience too, for the law, like our times, will and must change."
