This source is the bill that included the funding of over $1.3 billion for Plan Colombia. One of the most interesting elements of the text of the bill is all the safeguards in place to avoid human rights abuses. For instance, the bill required that the Colombian Armed Forces were required to cooperate “fully with civilian authorities in investigating, prosecuting, and punishing in the civilian courts Colombian Armed Forces personnel who are credibly alleged to have committed gross violations of human rights”. They also require that spraying will not be approved for funding until the Surgeon General reported that it was safe. Now, the military still committed human rights violations and aerial fumigation did happen, but it is interesting to see that some who were involved in the bill tried to add measures that prevented abuses but the funding still went to airplanes that assisted with aerial fumigation and that was what the effects of the bill really were in the end.
