No, but they didn’t beat him up because he was taking pictures; they mistook him for another suspect.
Of course they didn’t beat him up for taking pictures.
He was acting suspiciously in an area where they were seeking a suspect.
They are under investigation to find out how wrong they were.
If this guy didn’t resist arrest and he had a good reason to be there, ok. He’ll sue, and hopefully win, and get SAPD to figure out what happened here, hopefully
