I heard that on the replay, although I think that the last word was difficult to make out.
IMO, Nelson is doing his job by asking questions. He is seeking to paint a picture of what the officers perceived and experienced from their, or specifically the defendant's point of view.
Remember, Graham vs. Connor states that the "reasonableness of a particular use of force must be judged from the perspective of a reasonable officer
on the scene, rather than with the 20/20 benefit of hindsight" (BBM).

IMO, you do not have to like the questions that Nelson asks, but I think he has a very good reason for asking them, in his role as defense counsel.
