"You were teenagers in Gloucestershire, but you spoke in the patois of urban gangsters..."

It's becoming a sadly familiar tale...

After the guilty verdict, Josh's family called on lessons to be learnt to avoid similar tragedies.

But lessons about what went wrong are likely to be far harder to elaborate and spread than simply 'it's social media won dun it!'... 

They said: 'We feel all parents need to learn an urgent and desperate lesson to take closer notice and involvement in the lives of their young people, in particular on social media.

'Similarly far too many lives are being destroyed by knives, with social media an aggravating factor.'

Social media is, however, just the medium by which these animals communicate with each other; it's not the cause. That's something far deeper, and harder to reach.  

'Parents and communities cannot rely on the authorities to provide a moral education to their children.'

Sadly, for far too many, it's too late. They have relied on this, for far too long. And a generation of nihilistic killers has been born.
