The brown tone weapon is a device capable of producing a frequency that will cause hum ans to lose control of their bowels due and defecate in their pants. The frequency that causes this was discovered by the French and used on Axis forces during WWII. This weapon can also disrupt the equilibrium of a person and has been used recently on protesters at political conventions and meeting of trade organizations.
