Why aren't we allowed to keep/use guns for self defense again?
Because having a gun for "self defense" is a fallacy.
You are 100 times more likely to shoot yourself or a family member than use the gun for "defense"
The chances of gun suicide, the biggest number of gun deaths world wide, in your home go up by 1,000%
The largest cause of death of children in the US is gun shots, a lot of 'em when the kid finds Dad's gun.
There's more....
I read part of a study recently released, and they couldn't find ONE instance of a woman stopping a rape with a gun in the last 10 yrs. in the US. I don't remember the numbers for gun preventing crimes, but I do remember that you are something like 10,000% more likely to injure yourself with your gun than stop a crime.
For each crime a gun prevents, there are huge number of crimes committed with a gun.
... and being a conscientious Canadian gun owner: Are you going to ask the intruder to hold on sec there bud, while I open my gun safe to grab my Glock?.... no, no just a sec, the bullets are in the kitchen... I'll be right with you....
... or have you ever tried swinging a AR around INSIDE the house?
Are you gonna start BLASTIN' with your kids in the house?
WHY? Because SMART people have thought about it and wrote laws. Come up with any real data that supports the idea of guns being "self defense" and they'll be glad to listen.
... You DO know that the "Wild West" and John Wayne types are 100% Hollywood and never happened. Gun reality is the streets of Chicago. Highest "gun" murder rate in Canada? North West Territories... which has one of the highest rates per capita gun ownership in Canada... coincidence?
