Alain Magloire inquest to hear final witness today

An expert on police officers’ use of force is expected to shed light on the actions of police on the day AlainMagloire, a Montrealer suffering from mental illness, was killed.

Bruno Poulin will be the final witness in this portion of the coroner's inquest into the death of the 41-year-old.

Poulin teaches at the École nationale de police du Québec and is considered one of the top experts on the use of force in the province.

He was a witness at the high-profile inquest into the death of teen Fredy Villanueva at the hands of police in 2008.

Coroner LucMalouin has already heard from five police officers involved in the confrontation with Magloire.

They explained how they felt threatened in the standoff with him, and how he would not drop the hammer he was holding.

Const. Mathieu Brassard told the inquest he felt compelled to shoot the man in order to save the life of his partner.

Poulin is expected to dissect the police testimony and examine the surveillance video of the event to explain what he feels was done properly or not, and what could have been done differently.

The inquest will then take a break and resume on March 9, with an examination of the social and psychological services available to people living in a situation similar to Magloire's.
