"Showing that respect for all the people that are out there, whether they are white, black, Native American, it doesn't matter, we respect everybody. That was our goal (Thursday)," he said. "The actions of some caused us to have to use force in certain circumstances, which was very, very unfortunate."

Frazier called it "ridiculous" that someone was arrested from a sweat lodge and said he was calling in his tribe's police to monitor the local law enforcement response.

Archambault said the suitable vehicle for challenging the use of force against the protesters is a class action lawsuit against the state and law enforcement.

"The best way for success is to go after every individual law enforcement who fired a weapon at innocent people. We have to get badge numbers. We have to get facial recognition. We have to get these law enforcement that are from other states, whoever it is. And individuals who are harmed have to report what has happened," he said.

Archambault said he met Friday with a civil rights attorney from the Oneida Tribe of Indians of Wisconsin about the potential suit. The tribe brought recording devices to protesters this weekend so they could document future police action, according to a release from the Oneida tribe.
