kauffman, thanks for these links. Elsewhere, I have heard about implants snuck in certain groups of people for experimental reasons- (done without the person's knowledge) Then there are now those verichips that people are actually paying to have implanted. Right now, dogs and cats can have chips implanted for tracking reasons.
I don't trust any of this-- no matter how people think it will benefit. They already found these implants can cause cancer in the area they are implanted in.
It would not suprise me that we have been implanted through vaccinations, etc, in the past, because don't forget-- there has been a long track record history of past experimental things done with the populations against thier knowledge.
