Professor Sean Davison, the euthanasia activist who was found guilty of premediated murder, has completed his sentence of three years under house arrest and has vowed to continue the fight to legalise assisted death in South Africa. Speaking on the steps of the Western Cape High court soon after his sentence ended, Davison emphasized that he "did not cross a line" and acted with compassion when he helped his mother in New Zealand and three men in South Africa to die. He was joined by Dieter Harck who is terminally ill and suffers from Motor Neuron Disease. IMAGES AND SOUNDBITES
