clear statements on this now that was where he left but we know that from previous comments that the garson law does allow the people's liberation army to be used in the event of civil unrest so the possibility they left open the possibility that the people's liberation army could be used in hong kong. these protests don't seem to be going away they've been. continuing now for quite some time the protesters seem to be getting bolder the police are responding with even tougher measures using rubber bullets and tear gas as we've just seen how long will the authorities on mainland china and in hong kong allow this to go on well they waited at the umbrella protests this time it's harder i think for them to do that because the protests are very concentrated on focused on various areas there's a lot there's a lot of international attention. and this seems to be less even though there's a lot of violence in some ways it's less confrontational to the overall running of the of the territory so it's hard to say how long the government is saying that it will focus on economic areas so maybe they will
