On Thursday, an English court convicted Darren Osborne of murder and attempted murder for his terrorist attack on worshippers outside a London mosque in June 2007.

Although his target was innocent Muslims, Osborne’s rapid experience of radicalization-to-attack plot bears much in similarity with Islamic State-inspired plots. In recent months, counterterrorism services in the West have struggled with the increasingly short period by which individuals move from otherwise law-abiding behavior to terrorist plotting. This makes detecting and disrupting attack threats much more challenging.
