It is understandable that Latin American officials have grown fond of regional mechanisms, in part because they provide greater independence from Washington. This alone can be a good thing, allowing governments in the region to assert themselves and demonstrate that independence doesn't mean laxity.
But when officials have grown so fond of such mechanisms that they intend to use them to counter any criticism -- or worse, distort reality -- they go too far. It's one thing to decry unilateral finger-pointing. It's something altogether different to attempt to undermine a multilateral system, including the IACHR, that has proved its effectiveness.
Earlier this week the UCA radio station scored Francisco Flores' recent speech to the OAS (promoting his candidacy for secretary general) as hinting at support for a revamping of the inter-american system. I haven't been able to find a copy of the speech to get the precise details, however, just a press release on the OAS site.
