"In 1996, after curing myself with the Beck devices (blood electrifier and magnetic pulser) of the viral form of Chronic Fatigue Syndrome I started making the devices and selling them via the internet. Fearing the FDA I moved to Costa Rica. The FTC came against me in 2000 and I moved to Paraguay where the feds caught me 4 years later. I spent 21 months locked up for selling unapproved medical devices but they found no instance of customer fraud which I think in itself said to the ruling powers that this form of treatment is valid."
