The New York Times – The introduction to this article consists of still photos taken by a range of photographers at protests around the country.

If used appropriately, it drives people to flee the gas, which irritates their eyes, skin and lungs without causing serious, long-term injuries in most. But in cases where law enforcement misuses the agent, it can cause debilitating injuries. Prolonged exposure or high doses can lead to permanent vision damage, asthma and other long-term injuries. Research increasingly shows tear gas and other weapons that have been deemed by law enforcement as being nonlethal can seriously injure and sometimes even kill. There’s also evidence that the use of tear gas could worsen the spread of coronavirus. Because tear gas is indiscriminate, it makes it hard for the police to limit the impact to the intended target, and some experts question whether its use was necessary in recent protests. “The use of escalated force by law enforcement, all that serves to do is increase violence, increase injuries,” said Jennifer Cobbina, professor at the Michigan State University School of Criminal Justice, who studies race-related protests. “The primary mission of a police officer is to keep the peace and to protect and serve.” The widespread use of tear gas has prompted pushback, with some lawmakers calling for a ban of its use in Massachusetts and New Orleans.
