Yes, it’s always useful to save 2 minutes by increasing the chance of making the encounter lethal.
Seriously: why do some people need turn every single encounter into a time-critical emergency? If you can keep the offender from hurting anyone you can generally wait them out at very low risk.
American cops are watching this, saying, “Look how many people it took to bring him down!” and then adding, proudly, “Here one officer would shoot him and it would be all over in a few seconds!”
I saw them in Chengdu, China in February. Police patrolling the main square were already wearing studded forearm guards and had a stash of riot gear in one corner, including these and yes, quarterstaffs.
And, incidentally, fire extinguishers - apparently self-immolation is something the Chinese police worry about more than we get to hear about abroad.
Sooo … you basically asked the guy at the business end to load and prime it for you so you could shoot him? 'Cos otherwise, by the time you’d pulled it in enough to do that, he’d be close enough to use his sword or any other weapon. I can see why these designs did not persist for very long.
(Of course, the reality is more likely that once people really got the hang of firearms, these things were obviously unnecessary.)
nah, all that stuff was assumed you got one shot then closed for the nasty work.
then someone got around to inventing the socket bayonet for muskets, and all those pole arms got put out of work. it wasn’t until cartridge rifles that we could generally stand back and just shoot at one another like civilized people.
