Hya Tigerlil.
There is thou not quite sure what its called.
Suffice to say that yes, i will say it, certain parts of society are forgotten /cast aside by govs to the point that these groups feel slighted or a sense of mistreatment so they fight back in the only way they know - violence.
Its the same witht the riots in greece the ppl feel letdown angry that they have to pay the price of failure of the Govs - I Guess we all are,
All the time the rich get richer the poor poorer this divide will only worsen - along with it the violence.
On top of all this having a very impotent police force Too focused on anti terrorism and not on simple crimes like burglary /theft, antisocial behaviour allow this behaviour to propagate.
It seems the police are only interested in big headline grabbing crimes. -and speeding motorists?
Sorry to knock the police .
Give criminals an inch and they will take a mile ?
