the question of who are "they" is fair enough. but consider what happened to Martin Luther King and several other black civil rights leaders that very same day. What happened to his "killer" and what happened to the judge of the trial of James Earl Ray.
they are the people who sabataged Senator Wellstone, who decide what information the public and president is fit to hear, they are the upper echelon of the Intellegence or Military communities. Where members with big mouths get illegally committed to mental institutes, commit "suicide" or just go missing.
and if that sounds paranoid to you then obviously you are just poorly educated. To understand the nature of our government you need to educate yourself to the things we have committed in South America. The atrocities and evils done in our name by Henry Kissinger and his thugs.
