Aren't they (the Met) supposed to be a modern, intelligence led police force? If they were heavily outnumbered then that's a little bit of an intelligence failure isn't it. Their strap line is "Total Policing", I'm pretty sure that standing back watching the rioters burn and loot isn't what they had in mind when they came up with that.
What do you think will happen to ITN staff the next time there's a major riot if the rioters know the footage they are taking will end up in the hands of the police and used as evidence against them?
It already happens.
The likes of ITN, BBC and Sky camera crews were from memory attacked in the last lot of riots, and it's not at all uncommon for the vans of news organisations to get attacked at riots, and protests (I was reading comments from someone who works for one of the outside broadcast companies that supply the vans who was basically saying all they can do in such cases is hunker down and hope for the best).
The idiots don't need any incentive to go after reporters or anyone who is associated with the government/police/any big organisation, they do it anyway a lot of the time.
It's the same reason the likes of the Ambulance service get attacked, the scum simply don't care who it is they attack, anyone who looks either "official" or like they might have some money/be doing a job (any job).
Remember these are the same idiots who think a great way to protest the "inequalities in society" is to burn down their neighbours businesses and each others houses.
My personal opinion is pretty much the police should have been allowed to use water cannon and the like if not from the word go, from the moment the idiots started setting buildings on fire, rather than the "nicely nicely" approach the governments for the past 20 years have pushed, where it seems it's better for the Police to get put in hospital and for people to be attempting to kill them (the only possible explanation for throwing large chunks of stone at someone is to seriously hurt, or kill), than to have the Police look like they are hurting someone on camera.
The rioters are pretty much mindless thugs, the fact that the likes of ITN might be forced to hand over film footage (much of which was shown on air...) isn't going to make much of a difference to their attitudes.
