VANCOUVER -- Another defence lawyer is expected to deliver closing arguments today in the trial of a husband and wife accused of plotting to bomb the B.C. legislature.

Mark Jette will begin his final submissions on behalf of his client Amanda Korody.

Korody and John Nuttall are accused of planting homemade pressure-cooker explosives on the grounds of the provincial legislature on Canada Day two years ago.

Nuttall's defence lawyer Marilyn Sandford finished her closing submissions yesterday, arguing that undercover police officers manipulated the couple into carrying out the foiled attack.

Sandford described Nuttall and Korody's lives at the time as narrow and isolated, damaged by poverty and drug addiction.

She argued the main undercover RCMP officer involved in the sting feigned friendship, offered money, nice clothes, spiritual guidance and attention, making the couple feel important and validated.

"Think about the extent to which the undercover operation moved him away from his fantasies about rockets and nuclear submarines and onto the feasible, realistic plan of planting pressure-cooker devices at the legislature," Sandford told a B.C. Supreme Court jury.

"Think of the extent to which the undercover operation attempted to move him from the hokey and harebrained … to the doable and dangerous."

Sandford says it was the undercover officer who initially recommended Nuttall and Korody consider stowing pressure-cooker bombs under some bushes on the legislature lawn.

Nuttall and Korody have each pleaded not guilty to four terrorism-related charges.
