not a cell phone in sight. just ppl living in the moment.
Seriously though, I hope those are all burner phones and are turned off before going home. Because they will have IMSI-catchers/stingrays out to flag your device and monitor you.
Oh and if you ever find them using sonic weapons/LRAD to disperse your crowd, you can hold your placard paper (shiny side facing you) in front of your face and it should reduce the sound to a tolerable level.
