The Flashlauncher is non-lethal self-defense at its best.  This pepperball/flashlight combination is non-threatening, yet potent enough to stop an attack at a distance.  This is not a firearm.  If you are a missionary looking for a non-violent way to stop an attacker this may be what you need. 

I have an unfortunate update on this device.  It no longer fires the projectiles as it should.  Instead the CO2 cartridge hisses and does nothing.
