Ban YouTube and similar sites to prevent the internet being used as a tool for terrorism?

To combat terrorism, McNulty is attempting to reduce the potential for the internet to be used by extremist groups.

He is, according to a meeting on the 4th March: “Working with law enforcement and industry partners to target extremist use of the internet and where there is illegal material we are working to remove it.

“Under the Terrorism Act 2000/2006 this includes material that encourages terrorism”

McNulty will be “talking to industry, and those in the community, about what more can be done to protect communities from extremist exploitation of the internet.”

Would an easier option be to ban websites such as YouTube where potentially extremist material can easily be posted i.e. Saddam Hussein’s execution was never broadcast on television but was readily available on YouTube.

Such user generated content is difficult to monitor, and could be used as the basis for a terrorist attack.

Does this mean that all user generated content such as blogging sites and websites where members could easily be recruited or approached, such as Facebook should be removed too?

Are we being given too much freedom to express ourselves, such that it has the potential to damage our own security?

Is McNulty attempting the impossible in trying to track the internet, which is so vast and so readily accessible?
