Olympic Athletes Face Expulsion For Displaying Tibetan Flags In Room |Sky News|World News
Am I right in thinking the Olympic Village is an International Site not under the host nations jurisdiction but that of the I.O.C? I remember something about this in reference to previous Olympics and especially when the PLO kicked off in Munich.
If right then its no go for the PRC to demand this.
Please increase my understanding of this article in relation to the village. They will of course be during security searches of anything going in or out so its reasonable to expect they would enforce it then - or do they expect to get reports from the cleaners and then do raids?
