From Wayne Madsen Report:

"April 25, 2007 -- ABC News quickly amended its report concerning the ability of law enforcement to track prescription drug users in the United States. In a report on Virginia Tech killer Cho Seung-hui's possible use of anti-depressant drugs, "senior federal officials" told ABC News they could find no record of him [Cho Seung-hui] in the governments files on controlled substances. ABC News later posted an explanation of its first report that the US government tracks prescription drugs and their users: "Some readers may have inferred from an earlier edition of this story that the federal government keeps a comprehensive record of all prescriptions. The Drug Enforcement Agency says it does track prescriptions of so-called controlled substances including some mood-altering medications but not all prescriptions made in the United States."
The issue is to what extent does the DEA track prescription drug users and what prompted the government to check on records pertaining to Cho Seung-hui, who was reported to have been treated for mental problems in the past? The Psychotropic Substances Act of 1978 added mind-altering drugs to the list of official Controlled Substances. Prescriptions for these controlled substances have a "DEA Number" used for tracking controlled substances. The Cho incident and the comments and quick retractions by "senior federal officials" indicate that there is a secret federal government capability to track controlled drug users."

"Bush administration is prying into your medical records in violation of the law

We learned yesterday that the Bush administration has created a database of every single prescription drug user/patient in the country (that would pretty much be all of us). The database was created pursuant to a 2005 la that was intended to prevent the abuse of prescription drugs. Funny that this massive new database of your private medical information is now being (ab)used for a purpose that wasn't intended in or approved by the law.

The federal database of your private medical information is now being used by federal law enforcement to investigate crimes that have nothing to do with prescription drug abuse. We know this because yesterday ABC News disclosed that the feds checked the database to see what prescription meds the Virginia Tech shooter might have been on. How does the mass murder of students and faculty at Virginia Tech have anything to do with prescription drug abuse? It doesn't.

The Bush administration has created a massive database of your private medical records and they're now abusing it. Gee, what a surprise - the Bush administration secretly prying into our private lives in violation of the law. If they wanted this power, they could have sought it from Congress. They didn't. So they took it anyway, even though the law doesn't allow it.

Your privacy is gone, and it's not terribly clear that anyone in Washington cares."
