I can tell you that everybody that attended an Occupy Wall Street protest, and didn’t turn their cell phone off, or put it — and sometimes even if they did — the identity of that cell phone has been logged, and everybody who was at that demonstration, whether they were arrested, not arrested, whether their photos were ID’d, whether an informant pointed them out, it’s known they were there anyway. This is routine.
