There are many possible strategies for fighting charges of aiding and abetting a crime in Nevada. The following are some of the more common defenses: 1) No aiding or abetting. Just because someone knows about a crime or is in the presence of a crime scene does not make that person an accomplice. As long as the defendant did not knowingly facilitate the crime, he/she is not liable for aiding or abetting. 2) The crime has already been committed. Helping a known criminal after the crime took place is not aiding and abetting. However, prosecutors could instead bring charges for being an accessory after the fact (NRS 195.030). 3) No knowledge of the crime. A person cannot be guilty of aiding and abetting a crime if he/she has no knowledge that the principal was committing a crime. If the prosecutor cannot prove beyond a reasonable doubt the defendant knew or should have known of the underlying crime, then the charges should be dismissed. 4) The defendant withdrew from the crime. People who initially plan to aid and abet a crime may be able to escape accomplice liability as long as they notify everyone that they are no longer participating and do everything possible to prevent the crime from happening - such as tipping off the police. If the defense attorney can show that the defendant properly withdrew before aiding and abetting a crime, the criminal case could be dropped.
