An outcry for freedom will be heard far and wide

For a long time, Americans haven't cared less about Hong Kong. It was nothing personal. It was just that there was very little from Hong Kong that directly affected or interested them. The city rarely made headlines, much less the front page (one notable exception was whistle-blower Edward Snowden's revelations last year). Besides, with media consolidation and cutbacks, world news sections have been shrinking fast.

All that changed at the end of last month. Seemingly overnight, Hong Kong was catapulted onto the international stage, as thousands of people - many of them students - began their protests for universal suffrage.

Over the past week, I have had more inquiries and comments about Hong Kong from friends and colleagues than I'd received in all of my years living in the US. Yes, the protests were amazing, but the reaction was also amazing. There was a tsunami of media reports and streams of information via social media platforms.

"Are your friends and family OK?" my American friends inquired, disturbed after seeing images of tear gas fired into crowds.

Not surprisingly, Americans are all about having an individual voice, and those images - especially the ones viewed as police brutality on students - may have triggered memories of the Los Angeles riots in 1992 or, more recently, those in Ferguson, Missouri. There is also the collective memory of the June 4 protests in 1989.

In Hong Kong's latest protest, Facebook played a critical role in the curiosity and then genuine concern of my friends here. A myriad of Facebook profile pictures switched to yellow ribbons, while video clips of protesters fighting through the heat and crowds captured by smartphones were posted instantaneously to YouTube. Former students of mine sent me photos and a barrage of on-the-scene reports through WhatsApp. Indeed, information flowed fluidly among my friends in Hong Kong and here in the US, thanks to the internet.
