From Reason TV:

Norm Stamper is a cop who saw it all during his 34 years on active duty. As police of Seattle from 1994 through 2000, he was in charge during violent World Trade Organization protests in the Emerald City.

Stamper, who holds a Ph.D. in leadership and human behavior from United States International University, has emerged as one of the most thoughtful and outspoken critics of the war on drugs, which he believes causes untold misery, undermines effective law enforcement, and doesn't begin to pass any sort of cost-benefit analysis. As important, the libertarian Stamper believes that the drug war–and other wars on the behaviors on consenting adults–does great violence to the idea that we own our bodies.

Stamper is the author of the Breaking Rank: A Top Cop's Exposé of the Dark Side of American Policing (2005) and now works with Law Enforcement Against Prohibition (LEAP), a nonprofit created by former cops to "reduce the multitude of unintended harmful consequences resulting from fighting the war on drugs and to lessen the incidence of death, disease, crime, and addiction by ultimately ending drug prohibition."
