right, there's a contradiction here:
- if you're deemed to be on US soil, constitutional protections (4A) apply; can't be destroying "evidence" unless you're accused of a crime or found to have committed a crime
- if you're deemed _not_ yet on US soil, then how can you be charged with a crime under _US_ law?
The US views that US law applies worldwide. There is no requirement that you be anywhere near the US to be under US jurisdiction for an alleged offense against the US, according to the US.
Also, that constitutional protections are suspended within 100 miles of a land, sea, or air border.
