You have to steel yourself to read the victim impact statements of the parents of Breck Bednar, the 14-year-old boy murdered by an internet predator four years his senior, Lewis Daynes. Breck's mother, Lorin LaFave, on learning the news that her son had been killed, screamed so loudly that she burst her own eardrums. His father, Barry, told how he is now a "shell of a man, racked by grief". Breck's parents said they would have done anything to protect him.
In fact, they did go to some lengths to try to shield the schoolboy from danger before Daynes lured him to his flat and slashed his throat. Ms LaFave, suspecting that Breck was being groomed by someone much older than Daynes was, confiscated his computer. She discovered Daynes's identity and reported him to Surrey Police two months before the murder, giving detailed information, but even this was not enough for her to receive a call back. The information was not followed up until the killing. Another force, Essex Police, had been told in 2011, when Daynes was 15, that he had allegedly attacked a boy the same age.
Despite his mother's efforts, Breck and Daynes carried on communicating. Parents can be vigilant about what their children get up to online, but when faced with determined predators such as Daynes, or paedophiles posing as teenagers, they are up against devious, manipulative criminal minds who are several steps ahead on the technology. There is only so much a parent can do. So this is where the police come in - or should.
Yet the Child Exploitation and Online Protection centre (Ceop), an arm of the National Crime Agency, is struggling to cope with the reportedly tens of thousands of people engaged in online criminality, including viewing child pornography. I spoke to a senior technology official who described the challenge as an "ocean" of information - with only the resources of a tiny fishing boat to master it. At a time when Ceop needs more money, its funding has been reduced by 10% as part of overall cuts to the police budget.
In talks with Barack Obama in Washington this week, David Cameron will announce extra resources for tackling cyber attacks, like those experienced by US army central command on Twitter, including young technology-savvy volunteers who can work with GCHQ to counter the wave of hacking. It is clear that volunteers should also be recruited to Ceop.
I'd go further in wanting the police and authorities to have as many tools as needed to deal with online criminality - not only by predatory groomers such as Daynes and child pornographers, but terrorists and cyber criminals. As much as it pains my pre-motherhood self - an enthusiastic supporter of civil liberties - now that I am a parent I'm afraid I agree with the PM's renewed attempt at allowing the security services to snoop on internet data. Civil liberties should be protected, but not at the cost of our freedom from crime.
Ms LaFave knew the threat was real, which was why she tried to contact the police. We will not know the details of this specific case until an investigation by the IPCC has concluded, but there seems to be a general perception that the police don't take internet crime as seriously as "real" crime. Perhaps it comes from a lack of understanding of how the internet works, which is why Ceop needs more young experts to join their ranks. We have to stop regarding the internet as another country.
Breck's parents have set up the Breck Bednar Memorial Foundation - breckbednar.com - to raise money for computer education for young people. They have launched a wristband to remind teenagers of the dangers that can lurk online, with the slogan "Play Virtual/Live Real" - a motto we could all do with following.
