The schizophrenics are the only ones who pick up on it. The point in these methods is to control and stop a citizen from certain acts, to discredit them, or from displaying certain opinions in public. It's possible to do this to most people without them realising. Even the people doing it probably do not realise. They only have to be made to hate the person. The police are already carrying out these tactics. Therefor it's not some bizarre conspiracy and we are all being watched by different groups, with different motives, who want to manipulate us. What they're seeing is merely their own representation of the control grid. To others this may look like a delusion. I personally think they are mostly correct.
