The thing is, I saw 2 videos today talking about cooperation between HK police, Triads, and the Chinese government.
Then, last year I read another 2 other articles written by former police officers and a former ICAC staff. The ICAC staff voiced his frustration that ICAC top brass at many times (since Timothy Tong) prevented the investigations of certain big fish, while the former police officer wrote an article expressing his disappointment that HKPF isn't what it used to be. His reasoning was that some high ranking officers, after leaving the force, were hired by Triads and organized crime as consultants to get the inside understanding of how police do things, and then taught them on how to evade tax, breaches of the law, prosecution, etc.
Then today, I read a piece where a former Triad boss expressed outrage of what's happening, then said it's impossible that CY Leung don't know about all this, and that there's already been workings between the police and the Triads for dealing some backdoor stuffs for stability of territories etc, and I suppose this character is referring to something that's been around for at least 20+ years.
Then the next video I found/shown to me was a professor(I think one of the Occupy Trio) mentioning how he had talked to a former Triad boss who said the exact same thing, and how the police and the Triads had been cooperating, along with big businesses and the government for quite some time. However everything went downhill when CY Leung took office, who made things deteriorated a lot faster. He then further mentioned how the Beijing had idea that things could get ugly after the announcement, so there had been some talks where criminal organizations offered to do the rough cleanup for the HKPF, all because the HKPF had taps/leads on their criminal activity and they wanted to seize this chance to curry HKPF's favor or clean their records or something. He then said HK has never been so corrupted, and that the infiltration into the city began some weeks before all this mess, and there were promises that on 9/30 and 10/1 that they would do something big, and no one knows if they are gonna escalate.. Furthermore, if you include how that Falun bashers are on the streets that time and the police didn't do much to stop them, then it's not completely impossible. And if you do consider the gates to the government HQ were installed just prior to the announcement of the NPC, it seemed not coincidence.
I lost my hope further when I saw this video and the article because that means there's no cure for HK already. The pork-barrel politics and the ties between the police, Triads, governments, businesses, are all too connected.
I didn't bother posting the latter 2 sources because not only I'd have to translate, I doubt everyone will look at them. Furthermore, I can't verify the information on these 2 pieces of sources and they are controversial, so I rather not(also considering the crowd here are most likely going to dismiss this, or have a new flame war that might scapegoat me like I wrote it)
