Ayn Rand — 'There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. ... One declares so many things to be a crime that it becomes impossible for men to live without breaking laws." ― Ayn Rand

When was the last time you were armed or possessed a gun in your car and drove through a Post Office parking lot to drop a letter in one of the free-standing mailboxes?
Don't answer that. The walls have ears.
