Re: @ Mark 85 Two comments
Since you raised the point, supposedly, the Stingray system drops and ignores the phones of those the cops aren't interested in. I say "supposedly" because that's what the FBI claimed in court. Funny thing is, they've dropped charges against alleged crims rather than reveal how the system works or where the data (all the data) goes.
I wasn't discussing "right" and "wrong" originally but only what I'd do if I were a crim.
