Trump demands journalists correct stories on the use of tear gas. According to the CDC, it was tear gas.
The truth boils down to an exercise in semantics.
According to the Centers for Disease Control and Prevention: “Riot control agents (sometimes referred to as “tear gas”) are chemical compounds that temporarily make people unable to function by causing irritation to the eyes, mouth, throat, lungs, and skin.”
And, according to the CDC, “several different compounds” fall under this definition, and are employed by security forces, including military and police, in riot control situations.
Among others, they include chloroacetophenone (CN), more commonly referred to as “mace,” or pepper sprays — in other words, the compound that was deployed in Lafayette Square — and chlorobenzylidenemalononitrile (CS), “one of the most commonly used tear gases in the world,” according to an article in the British Medical Journal.
