The reality of the matter is under the US system and precedent, if the Supreme say it is constitutional it is constitutional. There is no objective reality in law only the courts reality. It is what it is.

Random foreigners killing them is the norm, not unusual. It has been that way since Alex da Great. They expect that so it does not raise a stir. It only seems weird to us. But ist does not mean they like us in any way, they just see us as the expected assholes like the Russians before.
Yeah, the agencies which 1. Aid US businesses (census, NOAA, Standards, Patent Office) 2. Try to educate Americans and 3. Produce and control Nukes and dispose of waste.
I watched from Eastern Canuckastan as it way after dark. Crikey what a pack of hoosers. I can't remember what it is but I want to cut these agencies note: Commerce includes the Patent Office, Energy includes NRC and production and care of nuck weapons etc. Of course Education does Student loans and we won't have any more of that nonsense.
