Secretary of State Hillary Clinton says the war on drugs "has not worked." But Secretary of Homeland Security Janet Napolitano is going full steam ahead.

Some Latin American leaders want the US to decriminalize drug use. Is that a cry of desperation? We hear from President Obama's drug czar and others.
