Stagi said she was standing close to the officer and filming him outside the U.S. Immigration and Customs Enforcement facility in Durango, a college town popular for outdoor recreation, when he hit her hand hard, causing her to lose her cellphone. Stagi, a retired hypnotherapist, said she then reached for the officer’s shoulder to get his attention. After she said he put her in a chokehold, she said he threw her down an embankment next to the street. She said she still experiences pain in her arm doing normal everyday activities, like putting on her jacket.
