Less Lethal has less likelihood of being lethal.
LEO and other First Responders go toward serious situations.
Civilians are well advised to learn to avoid trouble, evade trouble if trouble shows up, and if cannot deal with trouble.
Stop the threat!
One would not use a Less Lethal Fire Extinguisher - a fire (threat) needs to be stopped now!
I did not say the fire had to be "extinguished" , I said "stopped".
One does everything they can to avoid fires in the home.
Prevention with electrical wiring up to code and maintained, not over loading circuits, not leaving the stove unattended while cooking, smoke detectors and other prudent steps.
Evade with practice fire drills from various areas of the home to deal with fires that may be in various parts of home, or on property.
Deal with it. One might have to snag a box of baking soda kept near the stove to deal with a grease fire, this allows them to snag the kitchen fire extinguisher - family is in evade mode.
Next up is getting the bigger fire extinguisher to allow one's self or others, to evade, while waiting for First Responders.
Snagging the garden hose, maybe neighbors snag theirs and dealing with fire until FD and others can arrive.
I do not want a Fire Dept to show up with Less Lethal water, axes , ladders, anything else.
I want the Threat stopped!
Home Defense is the same way.
Specialty ammunition has a place for First Responders, whether it be rubber axes for a FD person to learn correct use of, or LEO rubber bullets for crowd control.
These First Responders not only have training, and continued training, they have Departments with insurance companies and all sorts of Legal avenues a civilian does not have.
LEO is NOT going to pop off rubber bullets, unless a Superior said to load up and do so.
If he /she does not follow protocol, they are in a heap of serious trouble!
Rubber baby buggy bumpers are the only less lethal item most folks really need in the home - then still these don't work, as wonderful child will still run over your butt and it hurts like the dickens! - Mentor
