So far there's no graffiti saying "Thanks, Justin!" on the new barriers, but in the wise guys of the world's defense it's raining today, and concrete doesn't take paint well when its wet. First nice day, they'll be out there.
Update: Welcome, vast swell of readers from Instapundit! Incidentally, today is May 2nd and we still have nothing better than "Incels" from police and government officials. Apparently the newspapers are printing "some guy in the jail said off the record that Driver guy said..." and that's what passes for news in Canada. Terrorism? Mental Illness? Suicide-by-cop? Something else? We don't know.
