But this is not exactly his quote when you read further than the first paragraph:
"Asked if slogans like “end one-party rule” – which is often chanted at the June 4 vigil – would be allowed in future, Leung demurred, saying there’s no need to get into the nitty gritty of legal definitions at this point, as this could ‘affect public feelings’ about the coming legislation."
"He also said whether the vigil itself could fall foul of the law could depend on what participants do even after the gathering is over – saying that anything that involves activities that are ‘separatist in nature’ may well be banned even in other countries."
He evaded the question when asked about the "end one-party rule" slogans, and repeat the line "separatist" will be banned when ask about the vigil.
Do I believe "end one-party rule" slogan will cause problem? I think so, and I do not support arresting people for just yelling the "end one-party rule" slogan. But I would like to see the detail of the law before I draw any conclusion.
