“They told me they were about to make the announcement and I think they stretched the announcements over 20 minutes. During the time I was there, I would periodically hear announcements,” Barr said. “They had the Park Police mounted unit ready, so it was just a matter of execution. So, I didn’t just say to them, ‘Go.'”

Barr said it was a Park Police tactical commander — an official he never spoke to — who gave the order for the law enforcement agencies to move in and clear the protesters.

“I’m not involved in giving tactical commands like that,” he said. “I was frustrated and I was also worried that as the crowd grew, it was going to be harder and harder to do. So my attitude was get it done, but I didn’t say, ‘Go do it.’”
