If there was "barbaric" coercion off camera, JVS will have to prove it. My impression from reading the Dutch editorial was that they have no specific allegations against the Peru authorities other than objections to the way JVS was paraded in front of the media with a bullet-proof vest. They felt making him wear the vest was prejudicial to public opinion.
It seems somewhat hypocritical for the Dutch media to object to JVS treatment as prejudicial, yet they also imply the Peruvian authorities are barbaric without presenting any evidence to support that claim. Goose, gander.
