Interesting point to ponder. Is it possible that Mainland China could send in 'agitators' to stir things up? - thereby giving them an excuse to 'restore' order. I just wonder the benefit of continuing the fracas. A bit of a David and Goliath situation. From the PRC's perspective it would cure the issue of having the HK thorn in their side. Would not be the first time 'disruptors' were sent in to stir things along to achieve a means to an end.
Conspiracy theory nightmare!. Ducks for Cover!
