This is literally the last thing the Hong Kong economy needs.

The situation in Hong Kong went from bad to worse on Thursday, as the unprecedented weekday protests - a violation of the tacit agreement between the pro-democracy movement and the business community not to disrupt weekday commerce -continued for a fourth day on Thursday.

After a squad of HK police officers earlier this week raided the campus of the Chinese University of Hong Kong, but purportedly found nothing, protesters accused them of unjustly harassing students, many of whom are simply trying to get through the semester. Just a day later, student protesters (the backbone of the increasingly radical movement) are openly making petrol bombs and have cordoned off their campuses, transforming them into literal staging grounds for the protest movement.
