As much as you can joke that you will get your gun before the the fictional invader got you it won't happen. I work for a major bank in Sydney and I have had drug addicts come in the middle of the day and attack me. They dont exactly hesitate. I've had someone od and vomit and probably die, the ambos took him away pretty quickly, I've almost been stabbed a few times, I credit my cricket skillz duckin bouncers for the reactions lol. It happens in seconds, there is 0 chance your gun will help
on the gun laws it wasn't something that has happened historically it just seems like we have a massacre gun laws get strict then over time we relax them then another massacre then the cycle repeats
in a perfect world everyone should be able to have guns and whatever else they want. But unfortunately the 0.01% of people ruin it for everyone else
