Tony Burke continues:

The thing that has made it harder is the old system of recruitment into different organisations and that sort of planning pathway – which was how we always used to think of terrorism – is something which doesn’t match – well, it still exists, that hasn’t gone away – but there is an additional form of fast online radicalisation with mixed ideologies.

It’s particularly targeting teenage males. And it’s that aspect which is new. The other hasn’t gone away. But that new aspect can lead to very fast radicalisation.
