Someone used the Duress feature and its now being prosecuted as destruction of evidence in the US:
"The US Department of Justice is attempting to prosecute an Atlanta resident in connection with the movement against the police training center known as Cop City because he had GrapheneOS on his phone, an open-source operating system that enables users to enter a passcode and wipe a phone clean.
The case, which had its first hearing on Monday, centers on a little-known US federal statute that makes it a crime to destroy property in an effort to prevent it from being seized. [...]
Agent Findley and several others repeatedly asked Tunick to open his phone during the interrogation, telling him they would seize it if he did not. When he finally provided a passcode, “the screen went blank, flashed several times and the phone appeared to restart”, according to the motion."

Does the project have some kind of warning or disclaimer on the site or in the UI about this risk?
Maybe it would be responsible to inform users of the potential legal risk associated with Duress.
