Where does the CDC define pepper balls as "tear gas"? It defines them as "riot control agents" in this document https://emergency.cdc.gov/agent/riotcontrol/factsheet.asp saying that these are "sometimes referred to as “tear gas”"
> 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.
I think we all agree that "gas/chemicals that cause tears" is "tear gas". Anyone saying that tear gas was not used is splitting hairs and their motivations should be questioned. This is not the time to be "technically correct" when police are using things like this on peaceful protesters.
I think the relevant question is, when arguing semantics with the US Executive Branch, is the statement more or less precisely accurate than the common use of language by the Executive Branch's leader and commander-in-chief?
They want to say it was just smoke grenades and pepper balls... Which the CDC defines as "tear gas".
