It is a very sensitive situation. I would respond first with some sympathy for your constituency and the people in Canada who are dealing with this. It is very tough.
In some ways it doesn't matter whether the motivation is political or whether the motivation may come from mental instability. We have had horrible incidents of family shootings and other things that have happened because young men, and sometimes young women, but often young men, commit a violent act for whatever reason—they're frustrated. From the security point of view, the first thing is to prevent those things from happening, to try to catch them before an individual does harm to himself or others. It doesn't matter what the motivation is, we want to keep people safe. Whether it's in a school shooting, the shooting in Montreal at the engineering school, or something of this order, we have to try to keep people safe.
Then always, inevitably and very humanly we turn to the question: Why? Was there anything we could have done? Would we have been able to do more if we had known more? This is why I raise the question of intelligence in the very local sense. What the U.S. has found in the vast majority of terrorist activities it has been able to stop, and even in the school shootings and individual acts of non-political violence that it has been able to stop, is that the intelligence that saved the day was from members of the community who knew a young individual or individuals and told law enforcement they were worried, and from law enforcement that listened, officers who said they heard what the people were saying and who worked with them to try to protect the individual from harming himself or others.
We saw that in Buffalo with the Lackawanna group. We saw it in Detroit. We have seen it in many incidents. I think we have to build trust among our law enforcement communities, our parents, our professionals working with kids in schools and the officials who are there to keep us safe. Worry less about motive. Focus on helping people and keeping people safe.
