If the police ask for you to turn something over, and you destroy it, that IS, in fact, a crime. That is destruction/tampering of evidence.
Here's an example: If you have a locked briefcase full of cat pictures, and the border agent suspects you have a briefcase full of cat pictures and ask you to open the case for inspection, and you give them a combination code for the lock that sets off a bobby trap that lights the briefcase on fire, that is destruction of evidence.
Second example: If you have a locked briefcase with nothing in it, and the border agent suspects you have a briefcase full of cat pictures and ask you to open the case for inspection, and you give them a combination code for the lock that sets off a bobby trap that lights the briefcase on fire, that is ALSO destruction of evidence.
Third example: If you have a locked briefcase with nothing in it, and a LEO suspects you have a briefcase full of cat pictures, they get a warrant and demand you unlock the case, and you give them a combination code for the lock that sets off a bobby trap that lights the briefcase on fire, that is ALSO destruction of evidence.
Fourth example: If you have a locked briefcase with nothing in it, and the border agent suspects you have a briefcase full of cat pictures and ask you to open the case for inspection, and you tell them you have forgotten the combination to the lock, that is NOT destruction of evidence.
Fifth example: If you have a locked briefcase with nothing in it, and the border agent suspects you have a briefcase full of cat pictures, they get a warrant and demand you unlock the case, and you tell them you have forgotten the combination to the lock, that is NOT destruction of evidence.
And just for fun: If you have a locked briefcase full of cat pictures, you empty them all in the trash before your flight, and the border agent suspects you have a briefcase full of cat pictures and ask you to open the case for inspection, and you give them a combination code for the lock that sets off a bobby trap that lights the briefcase on fire, that is ALSO destruction of evidence. However, if you unlock the case and show it is empty, that is NOT destruction of evidence, technically.
For everyone crying that the border agents have no evidence he committed a crime, please review the accounts listed above. If you destroy something after it has been requested by an officer with the right to request it, that is a crime. Regardless if the cat pictures are actually in the case, destroying the case is illegal. It is not on the DOJ to prove the destroyed evidence existed in the case. The phone, and the data inside, have the same legal requirements as the case and cat pictures.
The moment this guy decided to hand over the self destruct code, he royally screwed himself. Please note, for those who struggle with reading: he has NOT been charged with terrorism, or attending a protest. He has been charged with DESTROYING EVIDENCE.
What you miss is that border agents have the legal power to seize your phone for inspection without a warrant. By destroying data on the phone, he has tampered with evidence and obstructed an investigation. This is illegal.
Yeah, when you are on the border, you are subject to US border law, in which you have significantly fewer rights and protections then you do inside the US. This has been true since the late 1700s.
Again, he was NOT CHARGED FOR WRONGTHINK. Stop spreading misinformation. He was charged for destruction of evidence in a very open and shut example of FAFO. Had he wiped the phone before or even during his flight, and handed over a fresh device when requested, he'd have been just fine. It was the act of sabotaging the data with a booby trap code that is pushing him into the FO phase of FAFO.
