"If you ride with outlaws, you hang with outlaws" is an old slogan from wild times

It's simple enough to understand

You can't say you were only riding with them because you and they happened to be headed the same direction

You can't claim you didn't happen to notice what they were doing

Don't tell us you just couldn't figure out how to stop them

Were you riding with them? Yes? Okay, then: you're one of them
