Good video on surviving government interrogations:

 
1.  Maintain operational security and accept the fact you are captured by government.  Do not admit to being a hobbyist.

2.  Maintain grey man posture and appear to be a small fish - not a major hobbyist.  Don't stick chest out.

3.  Interrogators assess your eye movements and figure out what you do when telling the truth vs. lying.  Sometimes they are friendly with offering food and say that nothing will happen.  However, all you can do is state your name and ask for an attorney.

4.  Be aware of stress positions.  Developed in the middle ages but they still are used to torture today by government.  

5.  Overplay injuries.  Cry in order to garner sympathy and you might get extra food or a drink.  Always drink water of course if needed for an escape.
