Here’s a great example ( https://apnews.com/edd4ebdd7a245e568da69db38aea04db , third paragraph):

“[The mayor] put on a pair of goggles someone handed him and drank water but did not leave his spot at the front of the protest and continued to take tear gas as the demonstration raged — with protesters lighting a large fire between protective fencing and the Mark O. Hatfield Federal Courthouse amid the pop-pop-pop sounds of the federal agents deploying tear gas and stun grenades into the crowd.”

The federal officers are officially assigned to protect that courthouse. They built a fence but people still managed to build a large fire on the wrong side of the fence. It looks like the officers have a good reason to want the crowd to disperse, although I’m not sure that it’s a great idea to use tear gas so close to a fire. Unfortunately, as I understand it, if the crowd refuses to leave and tear gas has been ruled out, the remaining options are all very violent.
