-->-- ''Film/TheDarkKnight''

When a crook robs an individual or organization without realizing that the victim has criminal ties and the ability to [[IllKillYou hit back]] with means outside of the law. Realization is typically an "OhCrap!" moment.

Depending on the types of ties the victim has, the crooks might [[YouHaveNoChanceToSurvive get a warning]] that they've made a fatal mistake. Other times they won't find out until the first [[AndYourLittleDogToo drive-by on their mother's house]].

This is a subtrope of MuggingTheMonster. In that trope, the mugger is typically a {{mook}} and the monster is a main character, while in this trope, the robber is typically a main character and the victim is a villain.

For cases where characters are deliberately robbing criminals because they think they deserve it, see JustLikeRobinHood or KarmicThief.
