Totally Serious Ethics Question

Suppose you're a cop, and you're called to the scene of an accident involving a pizza delivery guy and an ice cream truck. The drivers are stable -- although unconscious -- and you're just waiting around until the paramedics arrive, when you notice that the car is full of pizzas, and the truck is full of ice cream.

Is it ethical to eat the pizza, or the ice cream, or both? Why or why not?
