Forensics Quiz

This is how I think the man died:
A twenty-year old man was running away from his psycho girlfriend who also happens to be a secret agent, so she has the necessary skills to take him down. She caught up to him on Thompson Creek Trail and shot him in the chest. He is later found supine and dead on the trail. Since the entrance wound was on the left lateral side near the third rib, I think that the rib fractured and punctured the lung. The bullet traveled to the umbilical region where it exited. While examining the body we found that the eighth rib on the right side of the rib cage was fractured as well. The rib was fractured because the bullet went through it and the rib punctured the liver. The bullet also passed through the heart on its way to the liver. I believe that the man died due to internal bleeding caused by the punctured lung, heart, and liver. Another less likely way that he died is since the lung was punctured, blood and liquids filled the lung. Also oxygen could not get to the brain, causing the brain to shut off. Another less likely way that he died is from external bleeding from the gunshot wounds.

Question on stem cells and the movie

If the mice or other animals (like the 1/3rd of the mice generated by Yamanaka's lab) that are generated by injecting iPSCs into developing embryos continue to form cancers or other diseases, will researchers ever be able to make it safe enough for humans? Would the governments and the people let it happen anyways? Is that a price that we would have to pay to live longer? Also do animal activist groups have problems with all this testing and research going on with these animals?
