Al-Abdaly's case slipped under the radar of British and Swedish authorities, just as the British government missed signs of radicalization by Abdulmutallab or terrorist ideologue Anwar al-Awlaki. Al-Abdaly was not on a list of 200 radicals being monitored by Sweden's national security service, Säpo. "He was completely unknown to the security service and there was nothing on him from earlier," said Tomas Lindstrand, a prosecutor speaking for the Swedish government. In the wake of the attack, British Prime Minister Cameron acknowledged "We have not done enough to deal with the promotion of extremist Islamism in our own country."
