As I said previously, if the guy had been a terrorist it might have been relevant. As we already know he had no link with terrorism, I couldn't see the relevance.
Your language skills could do with a brush up as well, 'canard' is French for 'duck'...
He left a terrorist safe house, was dressed like someone trying to conceal a bomb, acted suspiciously, and ran towards a train packed with civilians.
Hangs out with canards, looks like a canard, acts like a canard, dies like a canard.
Probably a canard...
