Thompson, Arnie, Skarpi, etc, NO anti-terrorist law has been invoked. What part of that can you not understand? The British Government used legislation contained in an act which covers crime, security and the interests of British nationals as well as terrorism. That paprticular part of the act is NOT concerned with terrorism.

In the event of informed opinion suggesting the government abused anti-terrorism laws or otherwise acted illegally, then its actions will almost certainly be subjected to judicial review. From everything I have heard so far, any such judicial review would uphold the government's actions.
