Hardee har har.Thank goodness, common sense returns to this thread.
I dono, if I shoot and kill someone during the course of my duties, I'm required to testify at the Grand Jury if I am not mistaken. Then the jury can ask me whatever question they feel the need to. Maybe that is the key, the ability to ask and answer any question that comes to mind without objections by the lawyers.
You may be required for your job (Garrity isn't applicable to GJ, I don't think).
