As I said, virtually everyone around me owns firearms. And, guess what? Nobody ever breaks into houses around here. I have only locked my doors a couple of times since I moved here, and that was simply because I was leaving for an extended amount of time. I don't even lock my car doors. Do you think that people might just be too afraid to risk getting lead poisoning to do such things?
You do realize how poor an example anecdotal evidence is? Stats have already been provided by Mike, which actually do a very good job of defeating your argument.
Also, if you took every firearm away from everyone in the US, people would just improvise firearms if they really want to kill someone and need a little reach. Please, research Zip Guns.
'Really want', you've hit the nail on the head. No one has ever proposed crimes are exclusively caused by guns: what guns do, is make it accessible.
most shootings happen in gun free zones.
And
all shootings happen because the shooters had access to guns. Why make it easier for them?
Which situation would you prefer, two people with guns having it out, which would likely end in two fatalities, or someone who's far more likely to have a knife: short range, less often lethal, harder (psychologically) to use?
Got to love how Vauxhall thinks traumatizing a generation of children is a good idea. Adults can need therapy after killing someone. Kids, they'll be rather less prepared.
