To handle this you could have a duress code that you could hand out that would make the system appear to be decrypted but only show the files you want shown when the duress code is used. That's the way most situations like this are handled. Now if they already know you have the data, then this won't work. If it was super-secure information (national security), you could give them another duress code that deleted ALL data, rendering you and the laptop useless. They might kill you for that though.
