When our guest makes a house call, it's usually because a suspected criminal has barricaded himself, with or without hostages, inside the house. Dr. Andrew Dennis is a sworn police officer and medical director of two Chicago-area SWAT teams. Dr. Dennis is also an attending surgeon in the trauma and burn units at John H. Stroger Jr. Cook County Hospital in Chicago. How is what happens in the emergency department similar to what happens in the field, and how do a surgeon's skills complement the work of law enforcement? Also, host Dr. Maurice Pickard hears how television affects the outcome of gunshot and knife injuries.
