Protest Policing in Vancouver

This article from the NY Times reports on some of the protest policing activities that preceded the Winter Games.  I have been critical of similar policing activities, including covert surveillance and apparent intimidation tactics, in the U.S.  It is a shame that such tactics have broader appeal in law enforcement communities.  China, no stanger to aggressive repression, seemed to imitate the "protest zone" approach used in the U.S. during the Summer Games.  Is Vancouver imitating the U.S. as well?  Are forces there consulting with U.S. security experts?
