I think you did the right thing. An officer can pull you over for speeding and choose to give you a ticket or not. There could be a host of different reasons to dictate their action. Who knows maybe it went to a needy family, maybe the officer kept it for herself? You showed the boys the correct action to take and I'm sure they learned something from this experience. Maybe driving around to some of the camps to find out who's deer it was could of been another option? Don't beat yourself up over your decision.
