Gun control is the main reason we have less violent crime in Canada. There is still violent crime here though, it's not a safe wonderland.

There is often impunity given to certain people for serious but nonviolent crime like identity theft and selling schedule 1 narcotics (the most illegal kind of drug in Canada). They simply keep what they steal or the profit and are allowed to carry on even if there is clear proof in possession by law enforcement. I don't think an authoritarian response is really what we need but it does make a mockery of the criminal system when this is the policy. And the damage is real, with the victims left to just put the pieces back together on their own.
