Isn't it generally illegal to film or take photos in a voting location? And now people are further spreading it? Considering how divided this country has gotten, an argument can be made this is dangerous for those in the picture.
The argument goes like this: Georgia, along with 11 other states, has prohibited filming and photos in polling locations, which is a legal prohibition in the public interest that has been upheld by the courts.
Show a rabid Trump republican a picture of voters at a polling place and inform them it's in a democratic stronghold and record what they say. I'll wait.
In public (and only when one would have a reasonable assumption of privacy, or whatever). Poll places don't follow those same rules. If they can prevent people from wearing campaign-related tshirts within X feet of a polling place, then they can prevent people from taking photos. Which they do.
