The story begins in 1995, when headmaster Philip Lawrence was stabbed to death outside the gates of his school whilst protecting one of his pupils from a teenage gang. The gang was called "Venom," and had been terrorising north London for months.
The brutal murder shocked the nation, particularly when it came to light that the killer was just 15 years old.
Learco Chindamo, a Filipino born in Italy, was the individual responsible. Hours after the attack, the swaggering thug was heard bragging about killing Mr Lawrence in an amusement arcade, and his callousness shocked even hardened police officers when it came to light.
Chindamo served 14 years for the killing, before being released in July of this year. He was spotted laughing, playing in the sun with his girlfriend's child - all pleasures denied to Mr Lawrence, a brave man who died doing what he saw as his duty.
The release had already caused controversy; even in modern Britain, the length of the sentence served was seen as something of a joke, but more than that - the government moved to have Chindamo deported back to Italy on his release and failed, because that would breach Chindamo's "right to a family life" which is guaranteed to him under the European Human Rights Act.
Obviously, once again, this is something denied to Mr Lawrence and his family forever.
All this would be bad enough; but a mere four months after his release, Chindamo was arrested once again for robbing a young man after threatening him with violence.
I highly doubt anyone outside of a select circle of elite liberals was surprised by this; but it does raise some disturbing questions, and it does help us to see just how diversity, apparently a positive thing we all must celebrate or be deemed morally flawed, affects certain areas of our cities.
The Daily Mail printed an article two days ago detailing just what had happened to the other prominent members of "Venom" - and it makes for distinctly uncomfortable reading. Of the six gang members tracked down, two are back in prison for recent offences, two have recently been arrested, a fifth is currently in hiding from the police and the sixth simply shrugs off his past as a mistake.
The article details three other horrific crimes the gang (pictured above, a very diverse bunch indeed) were involved in around the same period that Mr Lawrence was killed:
