You can, yes. Some people die putting their socks on and falling down the stairs (literally).
Guns are a bit more lethal than knives though, tbf.
Unless you're the Hulk or can warp time like Neo, there's only so many people you can take out with a knife or machete before you're taken out by the cops (either shot dead or tasered, depending on where you live).
Even if you use a vehicle to run people down, which is far more lethal, it's still usually not as deadly as an automatic firearm.
If you've got an assault rifle, the body count goes up a bit more... Even if you're a weed who can't bench press your own body weight.
That's why guns are banned in loads of countries and knives aren't. Knives are dangerous, yes. Guns are orders of magnitude more dangerous, though.
A psycho who runs into a Walmart brandishing a knife might do damage on a rampage and even kill innocent people. But give that psycho an automatic weapon and...
US logic is that if you give every citizen lethal firearms then a good citizen will usually be present to take them out. I'm not sure stats actually support this.
Plenty of trained security guards have been killed before they've even got their guns out their holster.
I think that's a happy myth, no offence.
Unless you're a trained sharp-shooter with combat experience and split-second timing, and on the ball, are you really gonna stop the next psycho nutjob when they're having a bad day and flip out?
Not sure the evidence is there.
The US has high school shootings all the time. Way more than most other countries. Where are the good citizens in the right place at the right time to take them out?
Does giving everyone access to lethal firearms really make you all safer? Genuinely curious.
(Like sure I get the whole government tyranny thing, but most shootings are not the govt being despotic; they're some guy who's flipped and has decided he can't take life any more for whatever reason so he's gonna take out as many innocent people as possible and go out with a bang or sth)
