Don't have any family or friends, either. If you refuse to talk and invoke your rights the government will just threaten to hurt those you love until you break and give up your passwords. From experience.

I liked it in Wrath of Man where one guy is acting tough as fuck until they bring his girl into the room.

Also, if you can, if you are encrypting data, use a hidden volume inside the first - that way you can give the government the outer password and they'll be happy thinking they have everything.
