A “principal by procurement” is a legal term that refers to someone who does not personally commit a crime but who arranges, encourages, or facilitates the commission of a crime by another person. This person is considered to be just as guilty as the actual perpetrator of the crime, because they were actively involved in causing the crime to be committed.
For example, if someone hires a hitman to kill someone else, they would be considered a principal by procurement, because they did not commit the murder themselves, but they were actively involved in arranging and encouraging the commission of the crime.
Under the law, a principal by procurement can be charged and punished in the same way as the actual perpetrator of the crime. This is because the law recognizes that the person who sets a crime in motion is just as responsible as the person who physically carries it out.
