Tottenham: police shooting followed by riots

[Carsten Wiethoff]

...but the only way we can see it working is if the entire cellular network is turned off in affected areas.

I can hear that statement from the police speaker:
"We are inifinitely sorry that you were unable to contact the police and the fire department when your house was burning and your sister was being lynched, but it was necessary to cut all communications in the area to prevent further violence."
:banghead:


Edit:
On review it looks like Cameron said:

Mr Speaker, everyone watching these horrific actions will be stuck by how they were organised via social media.
Free flow of information can be used for good. But it can also be used for ill.
And when people are using social media for violence we need to stop them.
So we are working with the Police, the intelligence services and industry to look at whether it would be right to stop people communicating via these websites and services when we know they are plotting violence, disorder and criminality.
I have also asked the police if they need any other new powers.

This goes more in the direction of internet censorship and not shutting off the mobile network.
