While I haven't looked into the two others, on one of the people burnt, Liu Guogeng, it seems important details were excluded:
On the streets, a widely circulated alternative version of events was that Liu had shot four people with his AK47 and was lynched after he ran out of ammunition. In fact, the photos of him hanging from a bus had been framed in such a way as to exclude the slogans scrawled in the dirt on the side of the bus: “He killed four people! Murderer! The People Must Win! Pay Back the Blood Debt!”
From Louisa Lim - The People's Republic of Amnesia, p. 17, just started reading this. It seems curious to me that the sources I have been given are really just repeating the justifications used by the state.
You also completely ignore how when troops were initially sent into stop the protests, the protestors blocked them for days, chatted with and fed, finally forcing the troops to return peacefully. It is the chinese state that began the violent supression of the protests afterwards.
And as I have commented elsewhere, random blogs and Reddit posts are useless sources to learn history from.
