Maria Lucia Karam and Annie Machon

Maria Lucia Karam is a retired judge from Brazil. She worked in the criminal courts for eight years, where she routinely cleared defendants of drug-possession charges on the grounds that laws criminalizing behavior that does not affect the rights and freedoms of others is unconstitutional. She has published several books and essays, much of her work being on the ills and failures of drug prohibition.

Annie Machon worked as an intelligence officer in the UK domestic Security Service, MI5, for six years in the 1990s. During part of that time she was responsible for investigating terrorist logistics, and worked closely with the Investigations Division of UK Customs.
