Then you're both wrong. Read:
FBI agents... were showing students a sketch of a man they want to identify. The sketch is of a man..., a law student said Thursday... The student refused to say what race the man in the sketch appeared to be. The FBI is trying to identify the man... said the student, who did not recognize the man.
The student NEVER SAW the guy. The student DID NOT provide any description of a person to the FBI... He is NOT a material witness. He simply described for a reporter the sketch that the FBI is showing around campus.
By the way, Dave S, in post #36 you are awfully presumptuous about my thoughts and intentions, evidently based on one pretty neutral (and factually accurate) 6-word statement by me on this entire thread.
You got me. I mistook your six words to be that the student was refusing to tell the police. I missed the part about the police were showing the sketch. Sorry. I was clearly wrong.
