According to Cameron Backs Eviction for London Rioters published in The Age today, "a London council became the first to begin evicting a tenant whose son faces unrest charges."
You can imagine a struggling family living in social housing. The son may be a rebellous teenager who spends his time rioting and looting. But then suddenly the whole family, including the mother and father, the daughter, the baby, the dog, etc are evicted from the house and left to fend for themselves on the streets simply because the son commits a crime.
This strikes me as grossly unjust.
