Ziamani, 19, was arrested in east London with a 12in knife and a hammer in a rucksack and subsequently convicted under the 2006 Act of engaging in conduct in preparation of terror. His lawyer had argued that Ziamani had been groomed by “more sophisticated and mature” extremists. Supporters complained that such a lengthy sentence was an outrage. It is not clear if Ziamani would have received it without the existence of the 2006 Act.
