I don't know about the fed level, but in my limited experience the haircut thing is not really accurate. I feel like looking at haircut and shoes comes from another and much more primitive era of law enforcement. A lot of undercover people work long-term as undercover people, and they have deliberately sort of "fellow kids" hair and facial hair.

Vibes and how well you know the person are more reliable than any specific checklist. If you wanted the checklist though, this is not a bad one.

One additional thing I've noticed as a tell is that everything is polished. Whatever type of "street" clothes they want to put on, the shirt tends to be neat and spotless, everything is clean, the facial hair is groomed. I imagine it varies by the skill level of the person, but in general cops don't like to be sloppy. Even their "sloppiness" costume will still be neat and presentable.

I mind-sung it to "She'll be Coming 'Round the Mountain".

I read the whole thing as “Fred”, and thought “That’s getting pretty dark for Scooby Doo. He’s not that bad”.

The UK Just Stop Oil and Extinction Rebellion movements were infiltrated and the activists received lengthy jail terms. I did wonder about their recruitment methods and it seemed that people randomly came into contact with the group, making identification of feds a problem. You would imagine that it's pretty difficult for the fed to maintain the required level pretence to remain undetected but they are probably terrible people to start with.
