I didn't mean a mug shot but a check in desk that has two angles under recorded surveillance that is time synced with a double sided scanner that you present photo id at. Person runs id
through the scanner so authorities have a baseline image of clothing & appearance tracked to id to help identify perpetrators of things like this:
It should only be a problem for someone who intends to do wrong or engage in rioting and I don't picture you as that type. I do picture you getting involved in helping someone who was in danger or in need & fighting off attackers though.
Funny how that would be a problem for you. I would much rather have it that way than having the NSA secretly capturing everyone's phone metadata on a real time basis and clandestinely accessing them all remotely to cull the images from the area of concern and identify the perpetrators that way, but I think differently than most.
If I am ever motivated to participate in a protest, I'm doing so because I believe in a cause and want to stand up & be counted, not to engage in rioting so I wouldn't have a problem with it at all.
