Concerning the recent case where the Gestapo charged someone with some kind of bullshit destroying evidence charge for wiping their own phone to keep CBP out of it at the airport:
The person being charged for feeding CBP a duress passphrase that wiped their phone in CBP's hands did the right thing and depending on what was on that phone may have kept others out of jail or even prison.
The rules in this situation are those of solidarity, and those of cyber warfare.
CBP is lucky a wiped phone is all they got. This could have been a cheap burnphone "encrypted" with a weak passphrase (1234 maybe?), and some strong ransomware.
Flash drives can be fun too.
Some years ago, someone near Boston set their heart on some flash drive fun. They got some cheap flash drives, loaded them up right nice, then salted the parking lot of a police station with the flash drives. The department in question was that of one of the suburbs near Boston, not Boston PD itself. All it took was ONE cop finding one of the flash drives and plugging it into his work computer. The whole department was botted, they had to pay ransom to Russian organized crime to get back everything possibly from their warrants to their payroll.
This was just flash drives found on the ground, not flash drives or a phone forcibly stolen from an opponent who had time to prepare for an attack.
Yes the Enemy can bring charges for destroying your own data much less botting their Cellbrite box. Would you rather face an obstruction/destruction of evidence charge or get slammed with far bigger charges supported by data on that phone? Still worse you may not be the only person in the line of fire.
If you are in possession of data that could harm others, it is your OBLIGATION to keep it out of the hands of their enemies without regard to any legal risk or other threats to yourself. If you cannot handle this risk, you also must not handle such data.
This is not optional, Obstructing Injustice is DUTY!
