What does "accessory after the fact" mean?

The term "accessory after the fact" refers to a person who assists another individual who has already committed a felony, with full knowledge of that crime. This assistance can take various forms, such as providing shelter, helping the person evade law enforcement, or providing financial support to avoid legal consequences. The key element defining this role is the individual's awareness that a crime has already been completed, distinguishing them from conspirators or those involved in the planning stages of the crime.

In contrast, the other options do not capture the essence of this legal term. Witnesses to a crime or individuals who report a crime do not provide assistance to the offender, so they do not fit the definition. Similarly, someone who plans a crime is an accomplice or conspirator, not an accessory after the fact, since their involvement occurs before the crime is committed. Thus, the correct understanding aligns clearly with the definition of assisting someone after the crime has already taken place, confirming that "B" is the appropriate choice.
