This is one of those things the other comment calling the law "non-autistic" is referring to. In the eyes of 99% of people, it's functionally the same thing. "Well teeeecccchhhhnicallyyyyyyyy I still have the data..." isn't going to make the security workers at the airport slap their heads and say "damn, he really got us! Go on through!"

No. They'll arrest you just the same for obstructing their search. Then they'll keep you in detention for a long time while you say "I can unlock it for you! You just have to let me out!"

You can pretend you have leverage and say they need to cooperate with you. But once you're detained, police and prosecutors don't really care about cooperation anymore. Their idea of cooperation is you giving them what they want immediately without question. You're made into an example if you don't abide.
