see my comment. they did the same thing to me in london it's a false flag op to cover up the fact that at least one of the people affected had an implant put in. i believe it uses the same frequency communication you would use to communicate with subs. it seems to work whether you are in the uk, canada, netherlans, or the US or flying across the atlantic. it's used for intelligence gathering, torture and interrogation. since the affects all appear as neurological and are on the inside and most people don't realize that the technology is advanced that far, people investigating it won't know where to look. the only real way to know for sure is to crack someones head and take a look. which i would volunteer for if there were no other way.
