Below is an article from the Salt Lake Tribune, in re Trump visiting SLC. In the first comment is a Picassa slide show taken by me for the public domain. I think you can view it with one of the three buttons at the top right, though I'm just testing this out now. I tried to capture a few of the array of unique signs that obviously reflect the views of the protesters. There is a video by the SLT in the link itself. I missed the police interaction captured in the SLT video.
Trump greeted by thousands of Utah protesters, some who blocked downtown Salt Lake City streets and faced off with cops in riot gear - The Salt Lake Tribune
