Yes of course anything sounds suspect to me, right. I am not claiming they didn't do it, just that when I consider these two things it doesn't seem to make complete sense, of course it might be the case that they merely denie it to make themselves appear innocent and the Chinese government evil or a possible other reason why they denied it. But it is not clear.
Now I don't know what the Chinese government would be willing to do, but would it really be that far fetched that these Syringe attacks have nothing to do with the Uighurs and that the Chinese government are merely taking advantage of this, or that the Han Chinese populace are merely being paranoid. In conclusion I don't think things are really clear enough to understand what was really going on.
I you saying that I should just accept things at face value, if I see something that appears wrong shouldn't I point our what "appears" to be inconsistencies, sure its no excuse if I could found out more that would explain away these inconsistencies and I may have failed to do so in this case.
To act upon what you do not know is foolish, yes? and that is what I have done in part here, but do you really know whom was responsible for the syringe attacks, maybe it was some Uighurs, maybe at the same time it has nothing to do with said Uighurs wishing to became independent. What evidence for the syringe attacks being about terrorism.
I am not judging this as proof that Uighurs or this woman had nothing to do with those attacks, that is you reading too much into what I am saying, those angry Han civilians could just as easily be the result of paranoia created by misinformation, whether deliberate or accidental. I mean what evidence do they have that the attacks had anything to do with Uighur Independence. Note

Sounds like paranoia in part, to me.
Just to be clear what I am doing is not outright supporting any view untill 'I' have better infomation.
