The shocking murder of a young French woman Amelie Delagrange in Twickenham in South West London, after she had got off a bus at night, bears some similarities to the murder in February last year of Marsha McDonnell, barely 3 miles away.
Given that this is meant to be a "safe" middle class suburb of London, and that the victims of these murders (and of a couple of similar serious assaults in the area) are young white females, there is intense media coverage and a high profile police investigation.
Interestingly, the murder over the wekend of a young male BBC employee Tom Brown on his way home in North London, is not getting anything close to the same media coverage.
The police have already released a still CCTV photo of Amelie Delagrange, taken boarding a London bus, an increasing number of which are fitted with up to half a dozen CCTV cameras onboard.
Since the victim was attacked some time after she had left the bus, nobody aboard that bus should be a suspect, exactly as in the case of Marsha McDonnell.
However, back in 2003, the police were obviously grasping at straws, and they then subsequently released CCTV stills from the bus which showed several youths, some of them Asian in appearance who had not come forward to be interviewed by the police as witnesses.
They had been on the top deck of the bus, whilst Marsha had been on the bottom one throughout her last journey. One of them was even on a completely different bus going in the opposite direction. None of these people should have been treated as if they were suspects in a murder case, yet that is exactly what the media coverage of these CCTV still photos conveyed.
Presumably the police were hoping that one of them might have seen something or someone through the grimy windows of a late night bus, brightly lit inside, when they were half asleep. It is just about impossible to see any details of people well away from the bus route at night.
Nevertheless, the police issued press releases with these youths' pictures under the headline of "wanted in connection with murder".
CCTV surveillance cameras did not prevent the murders of either of these two women, but, in the case of Marsha McDonnell, they were used to try to hunt down 4 of the innocent people who the system should have been providing an alibi for.
We will be watching closely to see if CCTV surveillance cameras on buses are yet again abused in this way, to hunt down the innocent passengers on the bus, and if this equipment continues to be touted as somehow making your journey home any safer.
