I think we should keep in mind that we are talking about a very small minority of the teenage population of GB,who,for reasons best known to themselves,have gone on the rampage.
Undoubtedly in the very near future we'll have the teams of experts trotting out all the reasons for the mob mentality,socially deprived,lack of parental control,lack of discipline,no future,etc,etc.
Sadly,the above can be said to have an element of truth,however no government overnight can solve a situation that has been festering for years,a million jobs can't be pulled out of the hat,the gang mentality seemingly cannot be controlled,the law is a joke,respect for people and property has gone out of the window.
Have you got a solution?,bring out the army,water cannons,hammer the little buggers into the floor,knock it into them,brilliant solution.
No ones got the answer,because quite simply we all lost the plot years ago when discipline went out of the window.
We have the tiger by the tail,let go at your peril.
