> Even if your encrypted laptop contains evidence, you cannot plead the fifth if the prosecutors know it’s there. As long as they can get a warrant and when they get the data say “see your honor? Here is the evidence we knew was there!”, it doesn’t fall under the fifth.
That sounds like the 'foregone conclusion' doctrine.
When it is a 'foregone conclusion' that the data is present on a device, you can be compelled to produce that data by decryption. However, if you are so compelled, the fact that you were able to decrypt that data can't be used against you. So they will need another way to tie you to the data.
An example is if police saw you had classified documents on your computer (by e.g. a video camera) and later confiscate the computer and find it to be encrypted.
