Preparing your own thoughts prior to testifying is one thing; allowing a lawyer to prepare your thoughts is rarely a good idea. Supposed Wilson had been indicted and had to stand trial. In some situations, his grand jury testimony may be used against him in the criminal trial, and if a skilled attorney can make the argument that the words that Wilson used are not his own, then that may very well effect the weight and credibility of his other testimony.
I still don’t see the problem. Witnesses prepare for grand jury testimony all the time. Since they are unable to have legal counsel with them during the questioning process, they better have their act together. He’s had plenty of time to think about how he’d explain this w/or w/o lawyer prep.
In this case, your point is Mute since the Grand Jury came back with a No Bill. The justice dept. has no grounds for Civil Rights charges - of course that will not stop Eric Holder’s minions from attempting their own lynching of this innocent man.
