You are wrong, it’s not an issue at all.
I think what RC is concerned with is that the jury (knowing that jurors aren’t necessarily picked for being the brightest candle in the church) might think
A: GZ was afraid to get out of the car
B: Remembered he was packing and could blow away anyone who looked at him funny
C: Overcame the fear and got out of the car.
Now, no one has come out and said B, but if I thought of it I’m sure someone else has too....
