this is a criminal law class and i want the cited examples to reference the school shooting that happened in parkland Florida on febuary 14 2018 in which the shooter was Nikolas Cruz. Many believed he did it because he wanted to hurt people who hurt him in which i think are means for a voluntary crime.
Directions
Actus Reus states that the crime must be the result of a voluntary act. Discuss the types of acts that may be included and those that are omitted from being a criminal act. Be sure to research a real-life case to discuss in your answer.
Be sure to give cited examples to support your posts. Make sure you cite your research in proper APA format.
