My point about political motivation is that what is going on right now is not driven by any desire to make a political point. There is no purpose or agenda to it and no-one in the mobs could tell you what it is that they hope to achieve.
That is not the same as saying there has been no political influence on this situation whatsoever. Politics are part of our society - but there are so many complicated, interelated issues that have got us to this point that it seems self-indulgent and blinkered to point the finger at the government (or the last one) and say "aha, I told you so, your policies have brought us to this". There are a million and one things that have brought us to this. Human culture grows and changes and reacts to all sorts of influences. If there was some way of tracing back all those influences from the current violence back through history you would probably find that things like the world wars, individual political figures, inventions, even things like the environment, as well as social policies, economics and more obvious influences, have all had an effect on society and have gradually got us to this particular point in time where we have a sub-culture of young people who are willing and keen to commit this kind of mindless, targetless violence.
It is so far from being simple that the knee-jerk "blame the government" response is really irritating and, in my view, distracts from the real issue which is that we need some fundamental social changes which can't come about simply by a change of policy, or redistribution of funding. It will have been slow deterioration of various values and systems that got us here and it will take an equally slow re-building of the same values and systems to get us back, if that is possible. It will take this government and the next 100 years of governments. History is full of peaks and troughs and we are in a trough.
The government (using that term for everyone who has been in power over the last few decades) has its share of responsibility and has to take the lead in trying to start to make changes, but there also has to be some straight-talking and acceptance of fundamental problems that may not be politically attractive or intellectually complicated enough for people to want to talk about on the news or political programs. Just pointing the finger at the government is side-stepping the reality of what is happening to people in these communities and it makes it look like no-one has a clue or cares enough to listen to what is being said on the streets and in the heart of these communities.
