Some of the better quotes I have run across

"Democracy is two wolves and a lamb voting on what to have for lunch. Liberty is a well-armed lamb contesting the vote." - Benjamin Franklin. (1706 - 1790)
"The only way Governments can induce citizens to surrender their rights is convincing them that by doing so, they will gain a measure of safety in exchange" - Thomas Jefferson
"I am concerned for the security of our great Nation; not so much because of any threat from without, but because of the insidious forces working from within. " - Douglas MacArthur
