SYDNEY, N.S. — The prosecution argued today that a Canadian soldier accused of manslaughter in the shooting death of a comrade in Afghanistan was trained "not to take wild, unaimed shots."

Cpl. Matthew Wilcox has testified he feared for his life, thinking somebody was pointing a gun at his back in his tent when he pivoted and fired his pistol.

He has told the military court that an instant after he pulled the trigger he realized he shot his friend, Cpl. Kevin Megeney.

But in closing arguments today in Sydney, N.S., prosecutor Maj. Jason Samson urged the jury not to accept the self-defence argument.

He reminded them of testimony by experts that Wilcox was to assess before shooting, and he argued there was not "adequate reason to use lethal force."

Midway through his submission, Samson told the jury that Wilcox's testimony was "not credible and should be disbelieved."
