Probably not what you had in mind, but Eat the Reich is a ttrpg in which you, a vampire commando, infiltrate occupied Paris to drink all of Adolf Hitler’s blood.

So the implication, not letter, of the 2nd ammendment gives US citizens the right to shoot cops if they are acting as an extension of a tyrannical state. I wonder if there is a case to be made that this executive order infringes on the constitution.
Of course, I don’t expect any 2A stans to care.

Unfortunately none of the families of cops that died from Jan 6 trauma were able to have it classified as “line of duty,” as far as I’m aware.
