[ Quoting from news story: ]
Airport security called the Mounties for assistance after an
unidentified man began pounding on windows and throwing chairs and
computer equipment in the customs area shortly after arriving on an
international flight at 1:30 a.m., Richmond RCMP Sgt. Pierre Lemaitre
told CBC News.

Before too many more people pile onto the "he was just being a jerk"
bandwagon, I should point out that, based on the reported behavior, there
is possibility that the man may have been autistic.
