Imagine a police state aware 'travel mode' that does the following: 1. Locks all your devices at the start of travel. 2. To log into your laptop, you need a code from your phone. 3. If your phone received a login request, it would record your location and ambient conversation to a destination of your choice. Put in a little delay between recieving the code and displaying it. 4. When you login with this code, you go into a low-privilege user account and/or locks you out of anything sensitive. 5. To unlock, you request another code from your phone. It only works if you are either at home.

You could carve out some exceptions for things you need while traveling that the bad guys who think they are good guys would already know.
