The article states that the area they wanted cleared was federally owned. On top of that it states that use of force should be used only if the protestors became violent:
When Barr arrived at Lafayette Square just after 6 p.m. in a scene that was captured on news cameras and elicited heckles from the large, peaceful crowd, the attorney general saw that the area had not been emptied, and told police to clear the area, the official said.
If federal law enforcement was met with resistance by the protesters, crowd control measures should be implemented, Barr had said, according to the official.
