The all rights reserved line confuses me the most here. Where and to what are they asserting copyright?

Are they claiming copyright on all that gibberish that they copied from a webpage somewhere or are they claiming that MDHS and the Census Bureau are violating copyright by printing their name and address on the letters?

Without a treaty with Mississippi (which I don’t think a state can enter into an international treaty to begin with) or the US Government, this chucklefuck can’t really assert that they want their copyright protected and enforced by the US when they are claiming that the US violated that copyright (still don’t know what is supposed to be copyrighted).

Another thing always frustrates me with this stuff is that anyone who has watched the news in the past 40 years should be well aware that the US and plenty of other countries don’t really give a shit about sovereignty unless there’s a treaty, a bunch of nuclear weapons, a big ass military, or a powerful economy protecting it.
