I agree and believe GF was frightened and terrified, and
not resisting arrest.
While reviewing the videos, I noticed a change in a stream of water underneath the police cruiser. Then realized it had to be coming from GF because the AC compressor is toward the front. I attached pics captured from the video.
In cases of extreme fear, terror and strangulation, incontinent urination is common. GF's autopsy shows his residual urine volume was 80 mls. And a man GF's size might have a bladder that can hold
>1500 ml. In other words, his bladder was pretty much empty.
