1) In most jurisdictions the use of deadly force to prevent the kidnapping of a minor is lawful.
2) I think, and one suspects that most reasonable people who have children, niece's and nephews, friends with children etc would consider shooting too honorable a death for them. A ignominious method of execution would be more appropriate. Like hanging.
