At least two possibilities anon can think of, one being simple Justice-Fantasy Porn. Legitimately protected by the 1A concept of free exchange and conceptualization fiction. Another idea, is like the theories of the Male Revenge Fantasy from Hollywood, inthat the Justice Fantasy diffuses to a large degree the real world demand for actual Justice.
If either/both underlay the production of the material it can enjoy protection in an honest free market. However, if it’s the product of a Counter Intelligence operation by wayward Government trying to smokescreen, cover its tracts and make a getaway… while insisting it enjoy the protections of the FIrst Amendment…
My feeling for such as the latter, can be described with heavy items smashing into the slimy traitor’s faces.
