Regarding training torture to foreign countries by “private security companies” and the current undergoing revision of the U.S. Department of Justice “revision “ of its investigative guidelines, I will offer my two cents:

It is easy to identify via the Internet through various federal agencies which U.S. based private companies are being awarded federal award (contracts).

Training foreign police (especially in Mexico), don’t be too naïve, the Federal, State, and Local Mexican police, including the Mexican Armed Forces,  probably know more about how to torture people than our own private security companies which are mainly staffed by former U.S. Military “special forces” and mercenaries.  During the 1980s, working for the U.S. government as a drug agent, we were allowed to participate in drug enforcement operations with our Mexican federal police in Mexico, except, we were not allowed to witness an actual interrogation and torture.  I agree with John Kirby's comments. 

It is my hope that we don’t go back 40 years and assign the FBI’s the mundane task of investigating “anybody” for possible ties to any terrorist organization, because they will be no longer have the manpower to investigate and prosecute other federal crimes that currently are considered "top priority cases for the FBI."  However, if this is the case, our U.S. government will have to dismantle…yes abolish, eliminate the U.S. Department of Homeland Security (DHS), and restore all of its agencies to their prior to March 3, 2003 (when DHS was created) status with their respective original mission and objectives.  Of course, our next 2008 elected U.S. president may change whatever this Bush administration and Attorney General are doing and start fresh…..I am looking forward to that!  Eight years of witnessing how our great country of us has become nothing but a “bully country,” one country which has been run by one person, which I highly question his mental stability (may be too much alcohol in the brain).  Thus there is some hope in the horizon and some light at the end of the tunnel.  I wanted to add the adjective word “superpower country” in my comment, but I doubt that we are still considered a superpower country.  If we continue with the way our federal government has been doing business, soon, we will become another “undeveloped third world country” and we will be the ones asking for financial aid to other "new superpower countries." 

If any journalist wants to know who is getting private U.S. grants to “help our undeveloped countries” – just surf through the official website of the U.S. Agency for International Development (one of the largest contractor of private security companies) and U.S. Department of the State to obtain the names of all U.S. based private security companies operating in foreign countries.  This is a matter of public record.
