“The first grand jury no billed him, It took a second try to get an indictment. History shows that is the sign of a week case.”
Or new evidence became available to the jury...
Not likely, Texas prosecutors have a history of submitting to 2, 3 or even 4 grand juries to get an indictment. They get to present their case without rebuttal, so they hone their presentation until they are presenting only the most effective stuff. Then it falls apart at trial when all submisable evidence is presented and rebuttal allowed.
I would bet that now that this prosecutor has his high profile indictment, there will be a quiet plea deal down the road.
