Tear Gas Controversy


“The point is we admitted to using what we used,” Sgt. Eduardo Delgado said. “I think the term ‘tear gas’ doesn’t even matter anymore. It was a mistake on our part for using ‘tear gas’ because we just assumed people would think CS or CN,” two common forms of tear gas.

What I said from the beginning: debate over a term instead of what happened.

WASHINGTON (AP) — President Donald Trump and some of his supporters are claiming authorities did not use tear gas against people in a crackdown outside the White House this week. There’s evidence they did.

Law enforcement officials shy away from describing crowd-dispersing chemical tools as tear gas; it evokes police gassing citizens or the horrors of war. But giving those tools a more antiseptic name does not change the reality on the ground.

Federal institutions such as the Centers for Disease Control and Prevention and the U.S. Army Medical Research Institute of Chemical Defense have listed tear gas as the common term for riot-control agents. Whether the common or formal term is used, the effects on people are the same.

Those effects were well documented when authorities forcefully cleared a crowd from outside the White House before Trump walked to St. John’s Church across Lafayette Park on Monday to be photographed holding a Bible.

“They didn’t use tear gas,” Trump said Wednesday on Fox News Radio. The U.S. Park Police denied using tear gas, yet acknowledged deploying a pepper compound, which the CDC and other scientific organizations list as one form of tear gas.

Authorities, who came from more than a half-dozen agencies besides the Park Police, set loose several wafting compounds, causing people to cough and gag as they scattered, their eyes red and streaming in some cases. They displayed the results of exposure to tear gas — tears, for example.

“Tear gas is anything that makes you cry,” said Dr. Lynn Goldman, dean of the George Washington University Milken Institute School of Public Health, speaking of chemicals used in crowd dispersal. “Pepper spray is a tear gas. But there are all kinds of other ones, too.”

Compounds that are listed as riot-control agents make people temporarily unable to function by irritating their eyes, mouth, throat, lungs and skin, the CDC says. They are “sometimes referred to as ‘tear gas,’” says a CDC fact sheet.

The Handbook of Toxicology of Chemical Warfare Agents also uses tear gas as an informal umbrella term for riot-control agents and cites pepper spray as one kind. In the unrest near the White House, officers shot plastic balls with pepper powder from what looked like souped-up paintball guns, and dispersed other compounds in a stinging fog.
