First, it's a difficult question to go in retrospect and speculate in terms of what would have happened.
Second, as you've seen in media reports, a number of reviews are being finalized as we speak. The Ontario police service is doing two reviews and the RCMP has done internal reviews. The result of these operational reviews will definitely lead to changes, will inform how the new director of the parliamentary protective service, with his colleagues, will carry out the security, taking into account new threats, taking into account the environment that we're in now.
It would be very difficult for me to speculate on what would have been different, but I can say with a level of certainty that the more you unify the chain of command for operations, the more you reduce the potential for confusion. I think this definitely is a step in the right direction.
