I used to be a cop. Mag-Light advertised their 5-cell flashlights at trade shows with the comment" "If you ever have to use it as an offensive or defensive weapon, it will not break." Whereupon the salesman used his light to demolish a wooden pallet.
I carried one for about six years. During that time I had several opportunities to use it in circumstances for which it was not actually intended (this was before Tasers and even before effective pepper-sprays). There are many goblins who interacted with my flashlight that can attest to its effectiveness.
Today, with Tasers in common use, the term "light 'em up" has taken on a new meaning. Especially if the gomer has been heavily into inhalants.
