Shouldn't even take a book to come to that conclusion, honestly. Frankly, I doubt anyone who is entrenteched in the propaganda around the event would change their mind no matter how much evidence you show them. For them, China is bad, so everything else must follow from that.
Even western media, at the time of the event, said that basically nothing happened in the square. It wasn't until they realised that didn't line up with the US position that they changed their line, but you can find old articles (including first hand accounts from diplomats in the area) that say there wasn't much.
I don't think anyone denies that some violence occured in the city as a whole, though it was very often levied the opposite way of popular portrayal. Especially because a lot of the PLA that were initially deployed were not even armed.
