In some circumstances, a crime does not need to be committed for a person to face criminal charges. Simply taking actions that show that there was an intention to break the law can be enough. When two or more people come together in agreement to work toward committing a crime, they may be charged with criminal conspiracy.
For a person to be charged with criminal conspiracy, action does not need to be proven. However, there needs to be sufficient evidence to show that the people involved had a full understanding that the actions they were intending to take would involve breaking the law.
