Ayn Rand on government threat to individual rights

Potentially, a government is the most dangerous threat to man's rights; it holds a legal monopoly on the use of physical force against legally disarmed victims. When unlimited and unrestricted by individual rights, a government is man's deadliest enemy. It is not as protection against private actions, but against governmental actions that the Bill of Rights was written.

~ Ayn Rand, The Virtue of Selfishness (1964)
