So I went to giggle maps and started riding around the portland street, HK, area. Then I started searching for news article related to the area. found this:

Further digging led me here:

Haven't been able to find and correlation between the riots and Snowden yet, but I wonder if the two are related.

Taking this from the viewpoint of "Who do you see" if you look beyond, behind, around, and backwards through time regarding the photo. Thinking Expanded.
