That's not really how the law works. You're not making a comparable analogy. You sitting at home or in a hotel room is legally not remotely the same as when you're being actively searched by a federal agent.

This is more like if the a police officer is about to do a pat-down search of someone, and they reach into their pocket, grab something, and rapidly swallow it.

You can destroy your property in normal circumstances whenever you please. If you delete a file in the privacy of your own home, odds are you're not doing so for the purposes of evading law enforcement. However, if you do it literally seconds before law enforcement is about to get a hold of it, it's pretty unambiguous that you're trying to destroy evidence.

That's the crucial difference here legally. Plausible deniability does not exist when you're destroying something because a police search is imminent.

We don’t need hyperbole here …. If authorities have a legal reason to search and you interfere with that, destruction of evidence is a crime. Delete all you want …. Right up until authorities claim the legal reason to search. Usually that takes a warrant: investigators must convince a judge there is a good reason

This also includes “when entering the country”. It always has. There’s nothing new here. There are so many things the current administration does to violate rights and due process, but this isn’t one of them.

The slippery slope here is “or within 100 miles”, but that wasn’t a factor here either
