By December 322 people were dead and 565 imprisoned. Even professionals involved in the uprising (lawyers, engineering majors, radio broadcasters and merchants) had been reduced to lives of "ever-changing safe houses, encrypted messaging apps and pseudonyms", with the Ortega government allegedly “hunting us like deer,” according to one dissident (Roberto Carlos Membreño Briceño). Human rights organization offices were raided, computers seized and observers expelled. Observers from the Organization of American States were expelled after releasing a critical investigative report of the government's response to the uprising. The report found the government had progressed from "using tear gas to rubber bullets, then real bullets and finally military firepower like assault rifles and grenade launchers", based on an analysis of videos posted on social media. At least 1,400 people involved in the uprising were hurt, although that the number was probably "far higher because most people were too afraid to go to public hospitals, where doctors were fired for treating wounded protesters". By July 2019 the international human rights organization Human Rights Watch called on the United States to impose sanctions on Ortega "and other top" Nicaraguan officials "implicated" in the crackdown on protests.
