It is unlawful for citizens to have weapons drawn in Sanctuary barring immediate danger to the citizen or other citizens' lives: this includes staffs that can be used in combat but does exclude properly made walking sticks that could do little harm in combat. A Watchman's opinion on the ability of a weapon to cause harm is always final.
The punishment for carrying a weapon and refusing to stow it when approached by a Watchman is a minor crime: generally paid through jail time, a fine, or in severer situations or for repeat offenders with confiscation and destruction of the weapon.
