From Washington Square to the Capitol, protesters on Saturday painted graffiti in Salt Lake City to memorialize their complaints.

Here’s a guide to what some of the acronyms and slang mean:

• 12: A reference for police. There are conflicting accounts about where it came from. Some believe it references the police drama “Adam-12” that ran from 1968 to 1975. The 12th Precinct was also the setting for the television comedy “Barney Miller," which appeared from 1975 to 1982.

• ACAB: All cops are bastards.

• BLM: It’s not referring to the Bureau of Land Management but rather Black Lives Matter.

(Francisco Kjolseth | The Salt Lake Tribune) Signs and graffiti cover the police department in downtown Salt Lake City as hundreds gather Saturday, May 30, 2020, to protest the death of George Floyd, the man who died earlier this week after a Minneapolis police officer knelt on his neck.

• FTP: The last two words are “the police." The first word is what you think it is.

• GMT: Gets me tight. That last word is slang for angry.

• “I can’t breathe”: The phrase was uttered by Eric Garner before he died in 2014. New York City police had placed Garner in a chokehold. The phrase has been used again in relation to the death of George Floyd in Minneapolis.
