if an IRS employee told you that you needed to delete a social media post, you'd obviously realize they have no authority to do so, just like a BLS employee for example, and you could tell either to go stuff themselves in as polite a fashion as you prefer

in the case of a police officer, our current society is one in which police officers can and often do immediately assault and/or shoot and/or kill you for doing or being something they don't like, regardless of whether you're right or wrong, and they can do so with little question and no internal criticism or retribution or punishment, which is an entirely different issue in and of itself

the same is obviously not true of Steve who works at the IRS. Steve would be tried for murder. So would Flaherty.
