One thing I did right in SERE training was not get caught. I would strive to not take anything into a government managed camp.

As for the rhetorical aspect of the question -- I would stash the entire kit so that it would be available after I found a way out of the camp. As you indicate, who's to say what they'd confiscate for the greater good. Once the crisis is over, I'll reclaim my stuff and do what needs doing.
