GW Bush is making one of his first newspeeking engagements in Calgary. Under Canadian law pursuant to international treaties, it seems we have plenty of legal justification to arrest him. With thanks to Observer151, Huffington Post:
Here's the relevant Canadian law on the matter - Crimes Against Humanity and War Crimes Act. This Act incorporates the 1998 Treaty of Rome regarding war crimes, as well as the Agreement for the prosecution and punishment of the major war criminals of the European Axis, signed at London on August 8, 1945; and the Proclamation by the Supreme Commander for the Allied Powers, dated January 19, 1946.
Read the section entitled 'Offenses Outside Canada'. Nothing in that section exempts Bush from avoiding arrest under Section 6 of this Act.
In fact, it appear that nothing in the Criminal Code of Canada precludes an ordinary citizen of Canada from making a citizen's arrest of Bush for crimes under this Act. Section 494 of the Criminal Code provides citizens with all the power they require.
Mandatory life imprisonment is called for where intentional death occurs as a result of the accused's actions:
2) Every person who commits an offence under subsection (1) or (1.1)
(a) shall be sentenced to imprisonment for life, if an intentional killing forms the basis of the offence; and
(b) is liable to imprisonment for life, in any other case.
