My understanding is you can’t actually be forced (legally) to give up your phone’s PIN or password as part of a police search, because it violates the 5th amendment against self-incrimination, even at the border. Now will they still find a way to fuck up your day if you refuse to unlock your phone, sure, but I feel like saying “I have a right under the 5th Amendment to not reveal my password” is going to be a lot easier to defend than “I intentionally wiped/locked/bricked my phone when you asked to look through it.”
Most phones can be accessed by forensic software. The more secure phones are protected as long as they’ve just been restarted but before they’re unlocked for the first time.
Some phones, like an up-to-date GrapheneOS on a supported Pixel, may resist forensic imaging after first unlocking but the information is in memory so there could potentially be zero days or other exotic methods of obtaining the data.
A duress wipe lets you know 100% that the data is not accessible.
