Actually, the majority opinion in the story  of Beijing resident Yang Jia  who recently rushed into a police building in Shanghai and stabbed and killed six police officers, wounding several others, seems to be on Yang's side. Since then, Yang's mother has mysteriously disappeared, Beijing police have been sent to investigate and, judging from what's being said online, Shanghai police are refusing to cooperate.
Another thing that remains is GenitalGate , the rumor/story flying around that Yang was beaten so badly by police last year when he was accused of having stolen a bicycle that his genitalia no longer functioned properly, and this was the reason for his revenge.
Related to that is the idea  that Roland Soong at EastSouthWestNorth put forth recently following the Weng'an pushup-riots, that either the most effective or most recent technique used by China's human flesh internet discussion directors aka the 50 Cent Party (will somebody please write them an entry on Wikipedia already!) in an age where enough netizens are savvy enough to get around keyword blocks, is to flood the blogosphere with disinformation in situations like these similar enough to divide portions of the online community and discredit the rest.
More information continues to surface  on who these 50 Centers are and how they go about their work, so, second, is it likely that this short personal essay which appeared (briefly, for some ) on all the usual major BBS forums yesterday was planted in an attempt to influence discussion? For example, how could the journalist mentioned below be so certain that any talk of Yang Jia's genital dysfunction was a lie? One commenter in the post linked to below notes that whoever posted it also only registered that account yesterday.
‘Fragmented thoughts on the Zhaibei police attack case “GenitalGate”‘ as posted on XinhuaNet  on July 25:
It's been a good few days since the attack on police took place, and all sorts of voices have rung forth on the internet, the most sensational of which has been “GenitalGate”. Because he'd had his genitalia ruined in a beating, he became enraged and a killer, taking six lives. Then the public became furious, the killer became a hero, and the murdered then deserved it. Flip that around, if this had been a cop who killed six criminals, that cop would just be accused of excessive use of force. He definitely would not have become a hero.
So…six cops, aren't these human lives too? Six innocent lives were lost and to go and so easily say things like, ‘killing people is wrong, but……”, don't you think that's a little cold-hearted?
The clearest display of social progress is respect for life. Just a short time ago, we mourned for the tragic deaths of our compatriots in the Wenchuan earthquake. There was no asking if they were good people or bad throughout their lives, there was only unity in singing praise for life, uplifting the souls of our people. Now, though, it's like people are ready to torture others just to prove that they were wrong, and why, because they were cops? So let me ask, if “heroes” like Yang Jia are worthy of praise, won't our society then become some sort of kill-or-be-killed barbaric jungle?
To not know how to respect life is to be backwards and primitive, so don't even think about talking about Lin Chong !
How Yang Jia became a hero is far beyond me!
Popular opinion has already painted Yang Jia as some sort of model citizen, his dad has said that he was “good in school”, the hostel he was staying at said he paid his rent on time, and regardless of if these are true or not, is that alone enough to make someone a model citizen? I see reports saying he kept to himself and didn't talk much, but then went picking fights with the neighbors over the most trivial of things, getting violent with them, a mad dog who needed no provocation, but when provoked would bite and not be able to stop, overall looking a lot like Ma Jiajue  who killed his classmates over a poker match! People like this definitely do exist in society, and normal people always keep a safe distance, so to avoid tragic loss of life.
Over the past few years, more than a few corrupt officials have been killed, and even more have been arrested, but new ones continue to appear. The reasons for this are complicated, but behind all the people cursing angrily like the tide, what I hear most are not moral condemnations or cries for the legal system, but signs of unbalanced mentality. If you think about it, when people like this become officials, why is it that they don't go find balance? Unhealthy values, this is one of the key reasons for unending official corruption. Police, as authority officials, are also people who come from the public, neither as good as gets propagandized, nor as bad as everyone says. Why is that that when something goes wrong police are groundlessly assumed to be bad? As for the incident of Yang Jia being stopped by police, I even heard that he was only stopped for riding an unlicensed bicycle in a pedestrian lane. Police around the world stop and check suspicious people on the streets, and every Shanghai resident afraid of being jacked in a rob-and-run will agree with these inspections. Of course, I don't have any basis to say that police have good attitudes, but then I haven't seen any basis at present to go and say that police are bad, and anyone who does is just speculating.
Is this information reliable? I did a search, and the earliest I was able to find was an anonymous MySpace user who posted it on the evening of the 2nd. The story is very stirring, but to this day there hasn't been anything more substantial to confirm this. The number of people who have spread it around is quite high, and that alone has nearly made it irrefutable fact, apparently even Phoenix TV even believed it. I have one journalist friend who through his connections was able to see Yang Jia's handwritten statement, and even Yang Jia himself has never said anything at all regarding the area below his waist! He told me that GenitalGate was a lie, but to put that in the news wouldn't please viewers, and that's why he kept silent. Because of this, I despise him.
“GenitalGate” is even easier to refute than the Zhou Tiger photos , because for that to be beaten bad and then recover, I'm afraid, is not that easy, so I don't believe that the police would have been able to cover that up. If it is true, Yang Jia wouldn't have killed people at a central police office, but at a local police station, because the police who stopped him were from a police station, and people go in and out of there every day to process hukous , which, unlike those people with too much imagination are saying, is not harder to rush into than a central police office building. This is common sense of which every Chinese person is aware. I can see that the people he wanted to kill were those who wouldn't give him money while he was being processed, because there is reliable information which proves that while he was being held by police there in Shanxi, he got them for tens of thousands of RMB, using pretty much the same tactics at the same time as the “Nailhouse” .
Alas, for this unfortunate “GenitalGate”! There is no so-called truth on this earth, only people who talk a lot, of stuff that becomes truth on its own.
Public opinion gets people killed! It got Qin Hui  fixed in the most humiliating pose in history, bringing about ages of righteousness, put Yuan Chonghuan  of the Great Wall up on the head-chop block, even led to our rivers and valleys falling at the hands of the foreigners. No matter how many people like or dislike this, what I want to say is:
Just because a story sounds good doesn't mean it's true, and this time, public opinion is wrong!
