More than 119,000 people have been injured by tear gas and other chemical irritants around the world since 2015 and some 2,000 suffered injuries from "less lethal" impact projectiles, according to a report released Wednesday. Physicians for Human Rights and the International Network of Civil Liberties Organizations, which produced the report, called it "the most comprehensive study on crowd-control weapons to date." The report on casualties from a largely unregulated industry cites an alarming evolution of crowd-control devices into more powerful and indiscriminate designs and deployment, including dropping tear gas from drones. Some of the injuries were fatal but it was impossible from the data to estimate the total number of deaths, said the report's lead author, Rohini Haar. The vast majority of the data comes from cases in which a person came to an emergency room with injuries from crowd-control weapons and the attending doctor or hospital staff made the effort to document it, Haar said. Protesters have been blinded and suffered brain damage from beanbag rounds. In November, the city of Portland reached a $250,000 settlement with five demonstrators in a federal lawsuit over police use of tear gas and other crowd-control devices during racial justice protests. But last month, a federal judge threw out an excessive force claim against an unnamed federal agent who fired an impact munition at the forehead of protester Donavan La Bella, fracturing his skull.
