First and foremost, what we're really talking about is prevention in those cases, and in particular, how we screen people who can access firearms. It's not just a question of screening the person—as is being suggested at present—at the time they first get firearms. How do we screen people ten years later, or five years later, or at the time they may have a marital breakdown or a family crisis?
What we see as one of the essential components of the current firearms program is the continuous screening of people who are in the firearms database as owners and the ability of people who are either living with them or working with them, if there's a problem, to call a hotline and say that this person is causing us concern because they've made threats. Or this person has some psychiatric problems and we're concerned because there are guns in our house. Or this person is demonstrating some unusual behaviour and we're concerned because we believe there are firearms. It's having the checks and balances in place to do that.
It's true that we're never going to solve or prevent every one of those types of tragedies. But certainly, having up-to-date information about firearms and about firearms owners, in a manner that's not intrusive but that allows the police to check that, is critically important.
