You are entitled to your opinion too. However, those who actually study their topics form the best opinions.
As I said, read the books. They are written by a M.D. who has no financial involvement, does not even mention Rife or any of the others, but provides solid scientific data on the use of electricity in the body.
I have also written to the CDC and they could not provide any information. The CDC has probably never bothered to try electricity because they are drug and vaccine pushers.
Also, if you are really interested, the FDA allows the use of electricity in treating orange juice, milk, etc. You can find the information on their site and there are links on the Zapper Forum .
