Even though certain machines are labeled medical devices, at some point, they will start confiscating them because people are "using the devices without a medical license."
I heard something a couple of weeks ago when the info came out about phone wire-tapping. Under the Patriot Act, Bushy wants to start "inspecting" people's private mail. I heard it once and the story was killed in the media!
I also agree with the above poster about bioworms and bioparasites. I found supporting evidence of this.
