The New York Times and Washington Post articles mentioned in my original post exist, but in archives. What I get when I do a search is a copy of the front page with the headlines but nothing readable. Maybe you can do better. So what I did next was search images since much mention is made of certain things. There I was able to find some things which lead me to believe that, as you say, the truth probably is somewhere in the middle. Who drew first blood? I don't know but the images show that, at least at first, the government used unarmed troops.
