John is driving his sports car on the interstate at 65 MPH, while a friend is hanging onto the roof of the car. They are allegedly practicing because they both want to be stuntmen. Of course, the friend looses his grip, falls off the car and is killed. John is arrested and charged with Involuntary Manslaughter in the death. As John’s attorney, can you explain how the prosecution will demonstrate his Mens Rea or mental state at the time of the incident.
