"The criminals are inside," they chanted.
Protesters refused early entreaties by city police officers to move off the hotel property. But they retreated when officers pulled out plastic handcuffs and prepared to arrest them.
"We told them it would happen," police Lt. Mike Ross said, "and that's when they decided to leave."
The group marched down the driveway and onto the sidewalk.
Salt Lake City Police Chief Chris Burbank showed up at that point and told protesters they needed to stay on the sidewalk to continue their rally without being busted.
"Go inside this hall there's murderers inside and robbers inside the building," one woman shouted at Burbank. "Go arrest the people inside the building."
Will Munger, of Utah Tar Sands Resistance, said his group wasn't trying to get arrested. Instead they were raising their voices against what they fear will be a trade pact that encourages the export of methane gas from the United States to other nations.
That would lock in an infrastructure based on fossil fuels instead of the community-based renewal systems that, Munger said, are needed to combat problems such as the Salt Lake Valley's severe wintertime air pollution.
Chris Davidson, head of security for Grand America, said protesters were not welcome on hotel property but had the right to protest on the sidewalk.
Top trade negotiators from the United States and 11 other nations along the Pacific Ocean began weeklong talks Tuesday at the hotel to try to narrow differences over a free-trade agreement.
The Trans-Pacific Partnership aims to increase trade among the nations to benefit all of them economically. Protesters allege the talks are conducted behind closed door and that drafts of the proposed terms should be made public.
