In The Last of the Mohicans, Hawkeye, played by Daniel Day Lewis, appears out of the forest to save the Major from a raiding party of Indians. When the Major grabs a gun and is about to fire at one of the Indians who is running away from Chingachgook (Hawkeye's father), Hawkeye stops him and says
In case your aim's any better than your judgement
Shouldn't he have said
In case your aim's **not** any better than your judgement
I can't imagine the Major would intentionally shoot the people that saved his life.
EDIT: Here is the action sequence. The scene in question is about 2:50 in.
