America DOES NOT have a gun problem. What it has is part of the American Dream. In fact it is the original American Dream, created upon founding of the country. They even amended their constitution to enshrine the Dream. Make sure everybody have the full opportunity to shoot and kill. Been shootin' and killin' non-stop since. Why just watch the hundreds of movies made. 

So treat these mass murders as traffic accidents. Not deserving of attentions, certainly not by foreigners. Since they don't care why should anybody else care. 

But I suggest Canadians must care. First, America's epic gun culture have corrupted Canadian culture due much to our media's obsession with all things American. We must resist, reverse this American corruption of cultural violence, killings for pleasure and profit impact on us. Second is the importation of guns into Canada illegally. As a result many  of our big cities have a gun violence problem. Too many guns available for a song. Yes, put up a wall!
