Thank you very much, Madam Chair, and, through you, thanks for the question.
Post-2014, there were a number of us who were meeting when the discussion was on the development of legislation regarding parliamentary precinct security. At that time, we looked at a number of models, including the Capitol Hill police service in Washington, D.C., as being a potential model. A number of those were brought forward to the government of the day and not adopted. Instead, they adopted the expansion of the PPS, which we see today.
A number of other areas—and my friend talked about crime prevention through environmental design—were things like one access point for walking traffic to Parliament Hill. Today, you can walk in next to the canal and come up in behind the West Block and nobody even knows you're there unless the camera happens to pick you up, and it certainly doesn't know what you're carrying in a backpack.
Those things were recommended and never adopted, because within 72 hours of that shooting, people wanted to get back to the way things were: making Parliament Hill accessible to everybody. They misunderstand the difference between “accessibility” and “security”. You can be hard on the outside and soft on the inside, like an egg. From a security perspective, that's really what they should be looking at.
There is a whole group of other things beyond Wellington Street that I think need to be implemented—or at least considered—and have not been implemented and that I don't believe were given sufficient consideration.
