There's video of the police carrying someone away, with his pants down. They drop him on his face at one point. Apparently the wrong guy.
Utah has what they call "constitutional carry." Extremely permissive gun laws. I'd bet there were several people carrying concealed in that crowd, not counting security and police.

Yeah, this happened with the shooting at the SLC protest earlier this year. A protestor with a gun was shot at by security, then accused of shooting the person who died. Open carry is allowed in Utah. Whether or not you think marching while openly carrying is a good idea. Unfortunately I understand the stress of the moment and it can be hard to figure out who is responsible while acting quickly.
