I don't understand this. I haven't follow the case recently. Can you tell me what happens?
Basically there are street vendors that sell stuff and curry fishball on the street during Chinese new year and city management was coming in to ticket and get them to get off the street since it is illegal. A bunch of those 本土派 (rough translation: Local Party/Gang) was using this excuse and state that we have to protect Hong Kong specialty (street vendor) and got around 300 people on the street. City Management called in the police and the 本土派 started to protest. Things got escalated and the riot police got in. The 本土派 attacked police and the police try to contain them. There were a few traffic police (in bright/neon yellow jacket) that was trying to get those people to back off but was attacked. One traffic police officer was retreating, while being beaten and he fell (I think he tripped) also. The rioter would not get back, so the other police officer fire 2 warning shots in the air to have the rioter backed out.
The 本土派 was calling people online to go on the street and riot. After the incident they even admit that because the police showed up, they went back to their "office" and brought in home made shield and weapon to protect HK specialty. The rioter also went online the second day and issue a call to have people on the street and attack police, border guard and also news media reporter on the street.
I find it pretty funny that some people from HK and those oversea HK people are trying to justifying the whole issue as fishball revolution and blamed the police showing up and escalated the issue, Nobody was initially arrested and it was the rioter that called in backup.
For those that only read English, I strongly suggest to read TsingTao, Ming Pao and the SUN (太陽報)English version. The English media either doesn't know the whole incident or is hand picking some interview to justify the whole event. (BBC especially. Pretty funny how non Chinese from the west even called out the bias). Also, tried not to believe facebook or social media "news" unless you have done study in the whole issue.
I read a comment online in one of the news article and I kind of agree with the person that posted. Here is what he said:
"Hong Kong people are so hard to satisfy. When there were street vendor on the street, the citizen would say that they are blocking the street or selling food that are unclean. They blamed the police as being in-effective. Now that they are enforcing the law, they blamed the police for destroying the HK specialty. What do you want?"
I really liked street vendor. A lot of foreigner would come to HK, so that they can shop on the street and eat on the street. Why would foreign traveler come to HK just to go to high class shopping mall when most of the brand names are from Western countries and are everywhere in the world.
People that were born in the 70s and 80s in HK (hell even some of my friend) were saying that street vendor are blocking the street (only some of them) and that they sold unclean food. The same group would go to Taiwan, Japan, Thailand and South Korea and find street vendor in those countries are awesome. I found them to be quite hypocritical. This pretty much forced the government to no longer issue mobile vendor permit and fix street vendor permit and have city management to enforce those law.
