Can you point out where you’re seeing those things specifically?
The “no civilians were injured” is coming from Awoo pulling quotes out of the links and “it was a violent mob that needed to be stopped by any means” is from Nakoichi. Both of them are my interpretations of what they said, only slightly exaggerated.
Here is a bit from one of the links already provided
First off, that bit isn't from the link unless you're summarizing it for me, in which case thank you.
But second, that article picks and chooses what information it wants from its sources even if the sources overall contradict each other. It uses a wikileaks source from earlier to say there were no deaths at the monument, but later uses a declassified document to confirm the death toll that says "TROOPS BACKED BY TANKS AND ARMORED PERSONNEL CARRIERS BATTLED CROWDS 0F CIVILIANS FOR SEVEN HOURS BEFORE REACHING THE SQUARE SHORTLY BEFORE DAWN TODAY BEIJING TlME . STUDENT DEMONSTRATORS BEGAN TO LEAVE TIANANMAN BEFORE THE TROOPS MOVED IN; TROOPS OPENED FlRE ON THOSE WHO REMAINED".
It says Amnesty International reapeats a bunch of lies and puts the death toll between 1,000-10,000 but the source it links as proof of this claim only briefly mentions Amnesty International, and says they put the death toll closer to 1,000 and doesn't mention any claims they might have made. EDIT: also, your summary goes against the "official record" from China: you're saying 100-150 of the dead were cops/military, but the article says "The 23 military deaths included 10 from the PLA and 13 from the People’s Armed Police."
It goes to great lengths to describe the student's movement and how barely any students were killed, but doesn't dwell too much on who was killed, and what their motivations might have been, why they were so willing to set fire to vehicles and put their lives on the line.
