A scary, intriguing look into the life of a(n alleged, since he is yet to be convicted) serial killer through the statements of people who knew him first hand. And that look expands to the neighborhood of South Central, Los Angeles, which almost looks like a third world country place. Very likely, hundreds of women, girls, have been abducted, tortured and killed by this Lonnie David Franklin. Considering the vast amount of evidence that was present very early on, this man could have and should have been taken off the streets pretty much straight away.

But Franklin was a man of (relative) stature, and to the L.A.P.D. most black lives appear to be not worth so much. The victims were mostly hookers addicted to crack, so he was even praised by them for 'cleaning the streets', if we may believe his son Chris. The picture that the women (prostitutes who knew Franklin, but also mothers of victims) paint throughout the documentary leaves hardly a shred of hope for the citizens of South Central. It is a community in which people seem to look out only for themselves, and in which drugs, violence and gangs get the better of many, and women like Margaret Prescod are admirable, yet rare voices for justice.

This is a grim tale, which is not over, and for the people of South Central, things are looking bleak as ever. The only positive outcome is that the Lonnie David Franklin is off the streets of L.A. forever - I at least want to assume that he will be convicted.

9 out of 10.

Nick Broomfield, I gather, is a well-known figure in documentary films, and he IS a little different from what you'd expect. He wanders in and out of the frame carrying the microphone and wearing earphones. He looks like a normal, middle-aged Englishman, moves deliberately, and sounds a little like Donald Crisp might have sounded as he approached adolescence. His voice is calm, dispassionate, and lacks drama. On the whole he sounds like a philosophy professor at some British boarding school, maybe Sidcot. "Next we met Bertrand Russell. Bert is a white-haired socialist. He once drove a garbage truck but is now homeless. Bert, how well did you know Alfred North Whitehead?"

In point of fact, we don't really get to know much about the suspected murderer, Lonnie Franklin. Broomfield has the invaluable help of a key informant, Pam, who takes him on a tour of South Central Los Angeles and calls pedestrians over for a few words about the Grim Sleeper. Without Pam Bromfield probably wouldn't have got as far as he did, since he's white. According to the anecdotes we get from the people on the street, Lonnie Franklin seems to have been one of those fellows who goes out of his way to help other people, although his friends do mention a few peculiarities -- a pile of stroke magazines in the bathroom, a proudly displayed .25 caliber pistol.

If we don't learn much about Franklin, we certainly get a good gander at the neighborhood and its residents. First of all, despite the bars on the windows and the gun shots in the background, it doesn't look nearly as squalid as the black ghetto near where I grew up, in Newark, New Jersey. Anybody moving from Chancellor Avenue to broad sunny Central Avenue in LA would take a deep breath and relax, the way retirees do when they finally step off the bus in Florida.

The police weren't involved in the film, so we get the African-American perspective on events. Generally, the attitudinal set is that the LAPD is incompetent and neglectful of black crime victims. There are exceptions but it's clear that there is a great big wall between the black neighborhood and the police force, as in so many other cities.

Broomfield doesn't show much in the way of political correctness. His informants speak for themselves. As an anthropologist, which is what I am, I would be very careful in taking some of their statements as literal fact.

One of the more admirable features of the film is that Broomfield, despite his narrative voice-over and his occasional intrusion into the images, is no Michael Moore. He's not one of the so-called Nouvelles Egotistes.

I regret to say that on the whole it was a little repetitious and dull. Too many anecdotes from a handful of acquaintances and relatives about what Franklin might or might not have done. It could have been pruned down to a fascinating one-hour show.

In July 2010, Los Angeles Police arrested a man on suspicion of murder, yet to date he has languished in gaol without being tried. How come? Lonnie Franklin Junior is a suspected serial killer. He is accused of the murder of a woman in August 1985. Victim number 9 - the only known survivor - was shot in November 1988.

It was not until March 2002 that another accredited victim was found. That near fourteen year hiatus led to the perpetrator being dubbed The Grim Sleeper. Although Franklin is charged with only ten murders and one attempted murder, he is suspected of committing many more. The evidence against him, which includes DNA, looks compelling, but at the moment his lawyers are playing what some might consider an obscene game to delay the inevitable. One of their tactics was to challenge the admissibility of a DNA sample as the fruit of the poisonous tree.

This documentary does not deal with the legal case against Franklin so much as the lives of those who knew him. Interviewer Nick Broomfield is shown around the area by a former prostitute, and meets a wide variety of people, including Franklin's son, who unlike his father is not even superficially a nice person.

All but one of Franklin's alleged victims were black, and all were apparently women a long way down the food chain. This and other factors like the failure of the police to warn that a serial killer was at large has led to the usual claims about race.

This is a long documentary, but one you can watch or simply listen to while multitasking. Doubtless there will be others about this case after Franklin's trial and likely conviction. As things stand, that should begin next month, but don't count on it
