I can't comment on the acid attacks, I doubt they're common. But the knife vs gun argument is also very clear cut to me. It takes very little effort or training to point a barrel and pull a trigger from across several meters or a courtyard. While a knife is actually not so easy to get into an expecting person. The knife would be most effective against unsuspecting persons but once a struggle breaks out it's down to physical strength and training. The knife vs gun thing hits close to home too because one of the very few school rampages performed here by an unbalanced student was actually performed with a sword because that's the only weapon the student was able to put their hands on. Despite being relatively far north in the country where there are more people with hunting licenses. And sure enough I believe they did manage to murder at least one person, it was a teacher or a teacher's aide who defended the other students. But that's where it ended. It requires significant strength and training to go on a killing spree with melee weapons, compared to firearms.
