(So the ban on streaking is among those rules in this spectator guide to the Olympics, pretty scintillating reading?) I think the Chinese authorities are trying to cover every area they can think of to get their backs covered. (What are they afraid of?) They're afraid of political protests, and they're trying to think of ways people could protest. (Like running naked?) Well if one can't take in flags, maybe someone could write something on their body and then run naked. (Have the Chinese gotten any kind of whiff for such plans?) One campaigning group in Australia have issued a protest resource kit for false tattoos and other such things to protest in China. (Are Chinese security teams rehearsing?) Oh yes, we've even seen some authorities rehearsing with sheets ready, they're taking this very seriously.
