Does the mass shooting in Toronto Canada show that gun control can never work?

Yes. The most prolifically gun violent regions in this country are places with the strictest gun control laws. It lets criminals know that the people have no defense in these areas and so they can act with impunity.

Right, it is mental problems that count.

So a measles outbreak in 2018 show that measle control can never work?

no to both questions.

Gun control has already worked in many ways. One incident does not negate that.

If you can’t solve your hunger permanently, then it’s not worth eating? Just because a problem doesn’t have a perfect universal solution, doesn’t mean we don’t have to keep working at it.

What I want to know is, why was this once so rare and now it is so common?

Isolated examples don't have any bearing on overall trends.

The gun homicide rate in Canada is 0.61 while in the US it is 4.62.

That is over 7.5 times the homicide rate in the US.

And people still die in car crashes ,despite wearing seat belts -- duh.

No.
