If someone is a gunfighter and bank robber or a highwayman, and in the

innocent people, and the Wanted poster for him says Dead or Alive, is it
wrong to shoot him in the back?

Ethically or legally?
It should be pointed out as recently as the 30s it was common for the
FBI to ambush criminals and shoot them in the back. Dillinger is a
good example. He was shot in the back of the head without a warning.
The rules are somewhat different now unless the HRT shows up. Then
bushwhack killings still go on. Ask Randy Weaver.
