Abstract: A device and method for countering, i.e., disrupting an attack by a dangerous assailant, particularly in a public space such as a classroom. A pressurized spray canister contains oleoresin capsicum (OC), a.k.a. pepper spray, in a gel formulation, and the canister is adapted for spraying a jet of the OC gel that is concentrated in the area of a person's head located up to 25 feet away from a user. To prevent misuse, the canister is securely stored in a box having a door with a latch for resisting non-emergency access to the canister stored in the box. A gel formulation has been selected for properties, in addition to its powerful pepper (OC) effects, that enhance defense including opaque, sticky, high density coverage, and brightly colored long lasting stains.
