When I hear stories like this, I immediately think of one interesting Ukrainian Bitcoin wallet developer who implemented a feature whereby if you enter an incorrect PIN code, the wallet will display a low balance. But in reality, if you enter the correct PIN code, the screen will show the wallet's true balance, even if it contains a thousand bitcoins. This special wallet, it seems, will mislead anyone who tries to access it without knowing the real PIN code. I find this idea amusing and very clever. It's precisely the kind of scenario the author of this thread describes.
This is a good way of deceiving criminals and protecting yourself from them. Maybe I would research this wallet and see how it works. It is common for the police to search citizens without warrants. This kind of wallet would be very useful if someone were kidnapped. There was an increase in the kidnapping of crypto holders in recent times. Maybe such a wallet would be a clever option.
But one would have to check how reliable or safe the wallet is before using it.
