Arizona law allows the government to prosecute all individuals involved or only one of the individuals. A prosecution against one person does not require the government to prosecute anyone else and a conviction against one defendant can occur even if the other individuals have been found not guilty.
Now, say you are the person charged with a crime and you know others are involved but the government does not. You can use this to your advantage and try to work a "snitch" deal, but most reputable defense attorneys will not assist a client in snitching on other individuals.
