US Law is always complicated because of the status of American U.S. Federal States inside the United States.
The Law of the U.S. is really is a sorry mess in some places due to the factionalists in some places.
Right now the Federal Government under Trump is really being pernicious right now.
A lot of this is by the Electoral College's design and the Ambiguous nature of both The Federal Supreme Court of the United States and also several provisions of the United States CODIFIED Constitution of 1787 (U.S.C, all written constitutional aritcles.)
The Interprative nature of the Supreme Court also plays somewhat of a role whenever those powers are abused by legalist strict constructionist Far-Right Justices on the Bench Of The Supreme Court (Federal) Of The United States.
Plus GW Bush the Younger and the Patriot Act made unwarranted police intimidation easier under the War On Terror, first with people in Wars Abroad, then First Trump Cabinet did the same with Foreign Residents in the USA, then the same under Second Trump Cabinet with USA Citizens of All Kinds and all other people.
The USA is not really safe like it was in earlier times for nudists, like it was about 12 years ago in 2013 under the Barrack Obama Cabinet.
Now, it seems Republicans in elected offices are really trying to intimidate "Different People" and "Immigrants" regardless, including some amount of the USA Citizens who happen to be "NUDISTS" inside BLUE DEMOCRAT CONTROLLED CITIES including Chicago and DC, as both cities are under a horrifying ILLEGAL occupation by THE EXECUTIVE BRANCH OF THE UNITED STATES GOVERNMENT right now.
