I think sword is a very mighty weapon if we are in Victorian era or something, it will be very useful for sure but now it is only for decoration and for other entertainment purposes and also sport and it's very awkward if you actually carry a weapon like a sword for protection in public people might not take you seriously, they might think you are a cos player . I prefer to carry a small knife instead or a balisong (a Philippine weapon).
Undoubtedly, you are right, especially when you pull Machete from behind your belt and hit someone with your paws a couple of times to break the bones, I do not think that someone else will contradict you. Only radical measures can stop the chaos.
I'm guessing that this will be the sales pitch behind having all humans be fitted with a neural lace. End violence, and dangerous behavior generally. Basically, a AI computer will be monitoring everyone in real-time and can stop them from doing anything 'bad.' Of course certain trustworthy people (e.g., the wealthy, higher level technocrats, etc) will not need one.
I'm sure your average soccer-mom would be all for it. Her kids will have a safe environment to grow up in with no bullying and that sort of thing. Many pros, and the cons (e.g., that the controllers would ever mis-use their power) are mostly crazy conspiracy theories.
