While I don't have the links, I've read some about his history. Just the parts you mention about his courtroom conduct confirm this. It's worth your while, and the defendant's while, to research this. Talk to local criminal defense attorneys, search the net, you'll be able to find this info and it could be critical in arriving at a strategy that would leave any jury ready to find the Philly 5 innocent, just from anger at the DA.
I'd give my eye teeth to be there during voir dire. That's going to be a dust up, all by itself!
May God bless you for your courage in standing up to this evil.
