I have one last point, I guess just to wrap up.
On December 16, I was in the Vancouver International Airport. As I was boarding my flight, a very large Ford SUV smashed through all the glass and ended up right at the counter where you get tickets, not 20 feet away from me.
Of course, that was an accident, but it could have been something else. I think there is merit to having some perimeters in our country.
