Should lone attacks be considered as terrorism?

Whilst the Government is not ruling out the possibility that the Woolwich attacks were part of a wider conspiracy, as far as they see it tonight there is no sign that that is the case.

Politically there may end up being broader questions about this - even to the extent of whether it should be classed as a terrorist attack at all.

People will be asking whether people acting on their own, mouthing an incoherent political philosophy, should be considered as any different to day-to-day criminality that we see in the courts on a regular basis.
