At the very end of the clip, Lazaridis says in closing the interview: "this [the topic being discussed] is a national security issue". He knew exactly what was being asked; and even if the phrasing was better, he'd have given the same reaction.
You should consider the possibility that if RIM are giving this type of access to India and the Middle East, then what other countries have this type of access?
If he had answered Rory's question, would something like the one I asked above be the followup?
Indeed, using "National Security Issue" seems more like a smokescreen in this case. RIM has bent over and opened their backdoor to various governments, and this CEO is trying hard to evade going on record about the issue.
