As Canadian border officer Lori Bowcock continues her recovery in hospital, the conversation is turning to whether Tuesday's shooting at the Peace Arch could have been prevented.

Border officials seem to be saying, no.
 
CBSA Executive Director Kim Scoville says he's reviewed the security footage over and over again.

"I've lived this non-stop since it happened. Our officer was defenceless. And I, quite frankly, don't think that really there was a lot that could've been done."

A motive still hasn't been determined as to why Andrew Crews allegedly shot Bowcock before turning the gun on himself.

Scoville says Canadian Border guards have some of the best training and equipment in the world.
 
As for Bowcock's recovery, she's apparently already asking about returning to work.
