I've been mostly looking at the Shanghaiist's liveblog of the proceedings, which pulls together a lot of great tweets and commentary. Another great source is China Digital Times.
Here for example are Bo Xilai and his former ally, Wang Lijun, once the police chief of Chongqing:
One thing I learned about Wang that I did not know before—apparently he has the reputation of being a real fashionista:
Wang designed police uniforms, boots, and raincoats. He personally oversaw the redesign, for "medical" purposes, of the uniforms worn by female police officers under his command. As well as fashion, Wang claimed to be an artist connoisseur and architectural expert. He took out over 150 patents for his various designs.He also supposedly liked staging false gun busts to pump up his image; also, torturing prisoners. It's enough to kind of make you glad that Bo punched Wang (or slapped him, depending on who you believe) when Wang informed him of Gu Kailai's role in Neil Heywood's murder.
And about that murder...apparently the reason Neil Heywood was killed was that he threatened to reveal the Bo/Gu's ownership of a French villa, and when Gu wouldn't pony up £1.4 "in compensation," he then threatened their son, Guagua. And if there is one thing we've learned from this trial, you don't threaten Guagua.
Rather than my trying to summarize everything that's gone on over the last three days, I'll leave you with the links to the Shanghaiist and China Digital Times liveblogs.
The Chinese leadership is in a tough spot here. They have to find Bo guilty of something, but the charges that they have the easiest time proving (or at least selling) are kickbacks and bribes of a sort that are standard operation procedure for officials -- cynical Chinese netizens have been making remarks that if this is all they've got, Bo hardly rises to the level of corrupt village headman, especially when compared to the millions or billions that the family of former Premier Wen Jiabao made during his years in power. And looking too deeply at the "abuse of office" — at those anti-corruption campaigns in Chongqing conducted to the music of "Red Songs" praising Mao and Maoism — could mean looking too deeply at Mao's legacy and at Mao himself. And no one in the current Chinese leadership seems inclined to do that.
