GrapheneOS duress PIN could land a man in prison

TL;DR

• A US man is being prosecuted after allegedly offering a GrapheneOS duress PIN that wiped his Pixel phone.
• The charge treats the alleged wipe as destruction of property intended to prevent a government seizure.
• The incident happened during a border search at Atlanta airport after agents demanded access to his phone.

What do you think guys? is he liable?

Journalists for example could be seen in a better light but as a normal citizen that sounds like he's liable. It's different if we offered no password at all.

CORRECTION: giving an officer your duress pin code and he uses it and physically sees how the phone acts and gets formatted GETS YOU IN PRISON.

SOLUTION: use the duress code before giving it to the officer WIHOUT HIM NOTICING for him not to see the phone reset itself

Damn, I hadn’t heard about this. That’s actually pretty crazy.

I'm fairly confident a decent lawyer could navigate around this bit of grey area of the law and argue the definitions in their favour. He's unlikely to get a guilty verdict for those particular charges, at least.
That said, I also wouldn't expect this to suddenly establish some broad precedent about duress PINs or phone wipes either. I'd imagine it's a case-by-case basis as these things often are, depending heavily on the specific circumstances and how the prosecution can establish intent. Will definitely keep an eye on the legal proceedings. It's rather interesting.
