The Los Angeles Fire Department is investigating an incident in which a firefighter “responded inappropriately” after being handed a letter to comply with the city’s vaccine mandate, a department spokeswoman said Wednesday.

The LAFD member responded to receiving the non-compliance letter by dropping his pants and wiping his buttocks with the letter, leaving fecal matter on the document, before dropping it to the ground, according to the Stentorians of Los Angeles City, a group representing African American firefighters…

“The LA City Stentorians are sickened and disgusted by this horrific display of unprofessionalism,” the Stentorians’ statement said. “To date, we have not heard from anyone from the LAFD administration condemning this act of blatant disrespect and harassment.”
