Rest in Peace, Professor Walter Williams. Walter brought a personal toughness honed as a Philly cab driver to fighting for freedom for more than 40 years.

Instead, he kept smiling and explaining and helped legions of folks recognize the folly of trusting government to save their ass. He recognized that the Constitution intended to leash politicians, not vex Americans in perpetuity with elected dictators.
