I've been contacted by teachers and parents concerned about this scourge. It's become increasingly difficult for parents and schools to monitor online behaviour. The online safety tips, they are great advice, but if we look at a couple of them: number one, become friends with your child in any social network environment they create. And another one: ensure that you can always have access to your child's phone to help them stay safe. Very sensible recommendations but, as any parent would know, very difficult. And schools throughout the country are constantly battling with students and their devices. Technology is changing quickly and legislation must keep up. Police need the tools if they're going to prosecute. As a police youth aid officer, I dealt with too many of these cases—that was a few years ago, and it's getting worse.
