(BBC) The threat from international and domestic terror presents a “breadth of challenge greater than it has ever been,” according to senior US and UK police officers who oversaw the successful prosecution of Anjem Choudary.
The Islamist preacher from east London is starting a life sentence for directing a group banned under UK terror law, and encouraging support for it online.
The officers say his case highlights the continuing danger posed by radicalisers — and the violent groups they support.
But they also say counter-terrorism forces are now battling a wide diversity of threats — including from a worrying number of people who don’t support an underlying ideology, but are simply drawn to violence.
