Since that time he knew, or had the opportunity to know, that the war in Afghanistan was illegal.
URGENT FAO David Cameron: Afghan War Unlawful in UK Law
I ask you as a matter of urgency to seek legal advice, since I believe the Afghan War is unlawful in UK law by virtue of it meeting the definition of "terrorism" in Section 1 of the Terrorism Act 2000.
I am aware that on the floor of the House you support the troop's actions. In so doing, you are supporting "terrorism" as defined in UK law and lauding the actions of those who are committing criminal offences specified in the Terrorism Act 2000.
for one description of the argument, and here for another (with a little polemic too, but a detailed legal argument later in the post):
I believe you have a duty to investigate this as a matter of urgency given that:
1. The British Armed Forces are acting contrary to UK law
2. British Officers would be liable to life imprisonment on conviction by virtue of committing offences under Section 56 of the Terrorism Act 2000
3. British soldiers who die or are maimed are doing so as "terrorists" as defined in Section 40 of the Terrorism Act 2000.
4. Use of public funds for unlawful purpose makes many civil servants liable to prosecution, in addition to specific offences detailed in Sections 15 to 17 of the Terrorism Act 2000.
Mr Cameron, in directing the United Kingdom's military action in Afghanistan is committing offences contrary to Section 56 of the Terrorism Act 2000.
On conviction, he will be liable to imprisonment for life.
