A criminal charge of aiding and abetting is known as an accomplice crime, and may be brought against anyone who helps with the commission of a crime. Aiding and abetting charges vary from state to state (and under federal law), but generally require that the defendant knowingly and intentionally aided and abetted the principal(s) in each essential element of the underlying crime. A person charged with aiding and abetting is often not present when the underlying crime is committed, but has knowledge of the crime before the crime is committed, and assists with the commission of the crime by providing information, action, or financial support. If the person aiding and abetting has a sufficient degree of involvement in the crime, the participation may rise to the level of being a conspiracy to commit the underlying crime.

In Wisconsin, aiding and abetting is covered under the state's criminal law statutes. A person can be charged with aiding and abetting if they intentionally assist in the commission of a crime, even if they are not present during the actual criminal act. The individual must have knowledge of the crime and take some action to assist or encourage the principal offender. This can include providing information, resources, or any form of support that facilitates the crime. The level of involvement required for a charge of aiding and abetting can vary, but it generally requires a showing that the defendant played a significant role in the crime. If the involvement is substantial enough, it could also lead to charges of conspiracy. In Wisconsin, the penalties for aiding and abetting will typically align with the severity of the underlying crime that was committed.
