I do know the full story actually. I'll summarize. In 2007 Guo Quan wrote a letter to the Chinese leadership asking for political reform, while peacefully founding an opposition party called the China New Democracy Party. Guo's writings were blacked out online and his name blacklisted from search. Guo was given a 10 year jail sentence in 2009 after being convicted under the charge "subversion of state power". Guo has 9.5 years of his jail sentence left.

If you have credible evidence that Guo was a violent, extremist terrorist funded by the West, I'd love to see it.
