Last night I looked out the window at 2am and there was a "road block" on our quiet little street. 4 policemen, 2 police vans and lots of flashing red and blue lights were positioned along the road. And no one, no one drove down the road.
At one point I thought it was a movie set, but no, it was simply a non event.
But then I thought that this was just Hong Kong being typically Hong Kong and thinking, "well-we-wouldn't-want-to-create-any-traffic-with-a-road-block-so-let's-do-it-on-a-small-residential-street." Also, "how-about-we-do-it-on-a-Tuesday-night-so-we-don't-ruin-anyone's-Saturday-night-when-they're-all-happy-and-drunk?"
Wouldn't surprise me.
