Sex or lunch, what would you do, six days in a row? If you don't find the baby soon, will she freeze to death? It appears to be a single gunshot wound directly under the chin; should we assume suicide or possibly foul play? It appears the grandfather had a heart attack and fell through the glass storm window. Do we remove the body before the young grandkids show up? It's against rules but we can't allow the children's last memory of grandpa to be crumpled and bleeding. Is that a gun in his hand or is that a cell phone? It's too dark, but the call was a man with a gun! If you're right you're a hero. If you're wrong you go to the morgue.
These decisions are made on a daily basis if you are a Chicago Police Officer. Hopefully you're right. If you're wrong not only do you suffer but your family does as well. No police officer wants to make a split second decision but at times that's all you have.
