Ridgewood Police Answers : Why do New Jersey Police Departments refer to the person who is accused of committing a crime the “actor”?
Here is a quote from Title 2C, NJ Criminal law:
2C:1-14. Definitions.
2C:1-14. In this code, unless a different meaning plainly is required:
a. “Statute” includes the Constitution and a local law or ordinance of a political subdivision of the State;
b. “Act” or “action” means a bodily movement whether voluntary or involuntary;
c. “Omission” means a failure to act;
d. “Conduct” means an action or omission and its accompanying state of mind, or, where relevant, a series of acts and omissions;
e. “Actor” includes, where relevant, a person guilty of an omission;
f. “Acted” includes, where relevant, “omitted to act”;
g. “Person,” “he,” and “actor” include any natural person and, where relevant, a corporation or an unincorporated association;
As you see, the “perpetrator” or “do-er” or “defendant” fits in with that legal definition of “actor” and that term is used in lots of the individual statutes use that term, like this excerpt from 2c:2-3:
“e. When causing a particular result is a material element of an offense for which absolute liability is imposed by law, the element is not established unless the actual result is a probable consequence of the actor’s conduct.”
Because the term is used in NJ criminal law, police just tend to use it on complaints, in their reports and news releases. Lots of states that use the “model; penal code” as the basis for their criminal law use the word “actor” when reffering to the accused
