Abstract

A system and method for implementing non-lethal chemical warfare against rampage shooters. A sound detection module detects a sound of a gunshot from at least one of a collection of sensors within a building. A sound location module determines a location of the gunshot by analyzing the sound. At least one emitter releases non-lethal chemical countermeasures from at least one at the location of the gunshot.

Claims

1. A computer-implementable method for implementing non-lethal chemical warfare against rampage shooters in a building that includes a plurality of sensors and a plurality of emitters, said computer-implementable method comprising:

detecting a sound of a gunshot by at least one of said plurality of sensors within a building;

determining a location of said gunshot by analyzing said sound;

releasing non-lethal chemical countermeasures from at least one of said plurality of emitters at said location of said gunshot.

2. The computer-implementable method according to claim 1, further comprising:

in response to determining that said location of said gunshot cannot be determined, releasing non-lethal chemical countermeasures from all of said plurality of emitters.

3. The computer-implementable method according to claim 1, further comprising:

notifying authorities in response to detecting said sound of said gunshot.

4. A system for implementing non-lethal chemical warfare against rampage shooters in a building, said system comprising:

a plurality of sensors for detecting a sound of a gunshot;

a plurality of emitters for releasting non-lethal chemical countermeasures;

at least one processor;

an interconnect coupled to said at least one processor; and

a computer-usable medium embodying computer program code, said computer-usable medium being coupled to said interconnect, said computer program code comprising instructions executable by said at least one processor and configured for;

detecting a sound of a gunshot by at least one of said plurality of sensors within a building;

determining a location of said gunshot by analyzing said sound; and

releasing non-lethal chemical countermeasures from at least one of said plurality of emitters at said location of said gunshot.

5. The system according to claim 4, said instructions are further configured for:

in response to determining that said location of said gunshot cannot be determined, releasing non-lethal chemical countermeasures from all of said plurality of emitters.

6. The system according to claim 4, said instructions are further configured for:

notifying authorities in response to detecting said sound of said gunshot.
