Witness (1985)

Character mistake: When Schaeffer, McFee, and Fergie walk down the dusty road to Amish village, Western gunslinger style, they make a silly mistake no cop would make - they assume that Amish villages are unarmed and undefended. No so. The Amish have no prohibition on guns and almost every house would have at least one hunting rifle or shotgun. The three bad guys are risking being shot to bits before they get halfway down that hill; they don't even make an attempt at concealment. (Wouldn't they also at least think John - a police officer - would still have his gun or might have got hold of a firearm from the Amish?)

Rachel Lapp: You said we'd be safe in Philadelphia.
John Book: Well I was wrong.
