Wiggy, I don't think you have any idea about the thoughts of Canadians regarding tragedies, shootings and similar. One thing is clear, you have been tainted by something and you are unable to let it go.
Travelling to almost all of the provinces this year, I heard about a lot of concern, not the "smug schadenfreude" that speak of; not even generally speaking. We all have friends in America, travel there, do business, shop etc. 

Time to change the channel...flip switches....reboot....you have no legs to stand on, figuratively speaking of course.
