The GJ should wait until January to announce its findings. Unless there's a blizzard going on, I think demonstrations are a foregone conclusion should the cop walk free.

Two words: Rodney King.

Not a bad suggestion. I have been there during the winter and it seems to always be cold and snowing/sleeting/raining.

The place is very pretty in the spring, though.

Seems that most demonstrations or rioting occur in warm weather. In my lifetime Detroit, Newark, Watts, the aforementioned LA King reaction have all occurred in warm temps or climates. Recall Occupy Wall Street fizzled out when push came to shove with the law and the winter months set in.
Question: Does Hong Kong have mild winters?
