On April 2, Amnesty International and other friends of human rights in Colombia will be protesting across the United States and in other countries to say "NO" to the threats and violence against human rights defenders which Colombia has recently experienced. Army-backed paramilitary groups have been systematically threatening and killing many such workers with complete impunity. Join Amnesty International as we tell the Colombian Ambassador that all the public relations efforts in the world won't wash the blood of human rights activists from the Colombian government's hands.
