If he grants clemency, its far from over.....
The real problem here is the extremely long amount of time between conviction and the carrying out of the sentence. Tookie has been on death row for 24 years. If the system carried out the sentence more promptly, the families of the victims would have seen justice a lont time ago, a message would have been sent to the Crips gang that he started, and this whole current debate would not exist.
If he grants clemency, there will be a massive effort for a new trial. Tookie wants to be free.
