If you find yourself in a dangerous situation and firearms are not allowed, then you might want to carry a can of Starting Fluid and a Cigarette lighter. Starting Fluid is Ether and is highly flammable. BAM! You have an instant Flame thrower that's good out to almost 10 feet. Don't forget...... Point the nozzle away from yourself. If you don't want to start a BBQ, you can just load their face up with it and it'll make them sleepy as Hell.
