In an interview with Spanish newspaper El Pais on Monday (as reported in Colombia reports), US Ambassador for Colombia, Peter Michael McKinley, when the question of Colmbian [sic] president Santos' recent remarks on drug legalisation came up, said that the issue 'had to be addressed.' This is of course a long way from endorsing a reform position, indeed he makes the US opposition all too clear. However, the statement is effectively an endorsement of the Santos position - that there needs to be a debate of the options, and legalisation (or as [Mexican President] Calderon puts it 'market alternatives') needs to be amongst them.
