This morning’s Metro (right-wing brain washing for the undiscerning commuter) contained an article of unusual horror:

A man of 66 was critically injured in an attack after he told a child not to drop rubbish in the street.
The man was punched in the head by a man who was with the child.
The attacker, the child and two women who had been walking with them, walked off leaving the pensioner bleeding in the street in Lewisham.
The victim is in a critical condition in hospital. The attack took place at 11.30am on Tuesday.
