Of course LEOs are NOT free to decide that some parts of the USA are 'de-constitutionalized'. They've crossed the line with that thinking. The border effects people on both sides in a negative way.
Not really, and it's nothing new. Customs authority on the borders clearly exceeds what would be constitutional anywhere else. It's why customs can tear apart a car without a warrant. It's been that way pretty much forever.
If you are believed to have crossed the border, US Customs and US Coast Guard can both do pretty much whatever they want. No warrants, no "probable cause", nuthin.
I'm not saying that's a bad thing, either. It's what makes the job possible. Any lesser powers and there would be no way for them to be effective at all.
“Did it turn out alright for them? What was the little trouble over?”
So far so good. It’ll cost them some cash but, could of been worse.
They were on vacation and got a little stupid. Lets just say the BP dog was fond of them.
