Re the cover up part, I guess I wouldn't use the term cover up, but the cop on the right seemed to know something was wrong. He was the one who attempted to arouse SG and had his hand inside the shirt to feel for breathing. He did a good job. If you watch his body language and his facial expressions, he reminds me of when there is a serious screw up in the hospital. Same face. I think he was the only one there who seemed to have a clue. IMOO
He could have done a much BETTER job if he had performed CPR. Why didn't he, do you think?
