Acid attacks aren't broken down into how many victims so I can't find out if there were multiple injuries: https://www.cnn.com/2018/01/26/europe/london-acid-attacks-20...
My point is that crazy finds a way. : https://www.reuters.com/article/us-britain-crime-murder/lond...
Your hypothesis is that people just use the next available weapon, which sounds logical, but is there any data to support it? Have the eurocrazies actually found a way, in general? Maybe most crazies just go and break furniture and laptops instead of stabbing when no guns are available? Maybe they just punch the person that they are unhappy with?
I mean, Europe is around for long enough time so we should have enough data to come to a definitive answer to the question instead of repeating it every time the subject comes in, right? Do people actually use knives when guns are not available and no significant safety benefit is achieved by the European approach?
Sure, there were some jihadist attacks but these are institutional attacks, I can't really recall having any angry person going on a rampage. In Europe, the act of an angry or crazy person will probably result in a break down in tears...
I'm not anti-gun, in fact when I was a kid I loved shooting with airguns and I bet it's a great hobby to shoot real guns but the European approach seems to be working.
Anyway, can you prove that my perception is wrong and in reality, people use knives and acid when guns are not readily available?
