"On one hand, taking away their weapons is a dead giveaway that they will need them. On the other hand, by the time conflict starts the players will already have opened the rulebooks and found the parts that deal with bare-handed combat, performing disarm moves, and using improvised weapons.
Players may blunder through dialog with shocking ineptitude, forget the name of the country they are in, or get confused about which side they are on, but once it comes time to roll for initiative they all turn into Sun Tzu." ~Shamus
