Question: What federal law enforcement agency wears a uniform that simply identifies the agency as “Police,” as opposed to FBI, U.S. Marshall, ATF, MP, etc.?

Three that I have worked with: NNSA OST, DOS DSS, and USSS CAT teams.

None of the federal law enforcement agencies that you reference would have been involved with this type of operation, except perhaps USSS CAT, and their uniforms clearly have the words “Secret Service” below the word “Police.” This is fake news.
