The bad guys quite often have the same costume. Hat, hoodie, and jackets. The clipboard however is a heck of a prop. Maybe these guys are census workers in training. Who knows. Maybe the pictures aren’t even from Blink. Who knows.
What I’m trying to figure out is why the hell would someone from the Blink Community would recognise these men. You would have a MUCH better shot at IDing these guys via social media paths.
