This is not a thing that has happened over night nor is it a thing that can be rectified quickly by overrought soundbites and kneejerk reactionary changes to this or that individual policy.
The root causes are systematic and endemic; and now multi-generational thing. We are reaping what we have sown from years of policy making that put the individual above society as a whole.
More than anything the people the perpetrate these crimes are a product of the massive divisions in our society. We have created an enviroment where 'evil' can fester and rippen; masses of dissenfranchised wrongly raised youths who respect the wrong things and gather together because they have had no opportunity for other structure in their lives have been allowed to drift away from society at large forgotten and ill-cared for.
Respect for all forms of authority seems too often crippled; it is losing its grip, its power to prompt the right course in the individual because of the selfishness and entitlement our culture has promoted a priority, as worthy, for too long. The messages we have been voting for have been wrong over successive parliments, and we have invited this virus into our lives as a result.
Parenting has been devalued and demoted. Governments have become heavy-handed in thinking they can control by direct policy things that should be promoted by classes in good parenting before we get to become parents!
We raise up the wrong idols for our youth. Celebrity culture teaches them the wrong lessons.
There is a lack of coherence and cohesion to our society. A lack of idea of a common good and core values. We focus on the wrong things, the easy answers at every turn. Education, family structure, investing in people and communities on the ground (yes including policing and stronger prison sentencing for the things that really matter to the public) should be the bedrock of all our policies instead we look to business and money making at every turn. Politicians too often pander to the quick headline and their own careers over working to put the difficult things right.
Take a look a this comment by some alt commentator and ask yourself why is he making this an either/or argument?

It is surely evident that the first elements on his list are linked with the second. The one is the breeding ground for the other. Ideology stops us seeing the truth so often. We are so obsessed with standing our ground, we fail to see the validity in the argument of others. We define ourselves by our devisions instead of by our common ground.
It's going to take a bloody long time and a lot of work to reverse the trend that prompted this thread; it starts with the almost impossible job of finding the right people to elect in this country.
