A man walked up to Dick Cheney, calmly told him he thought his Iraq policy was reprehensible, and walked away. A few minutes later he was arrested by the Secret Service, in front of his 8-year-old son, for "assault".
When he asked what would happen to his child, the Secret Service said, "He can be sent to Child Services." Luckily, the boy found his mother and was safe.
But the citizen who practiced his free speech spent a few hours in jail before he was released.
