What is required for an officer to arrest a person in a public place?

For an officer to arrest a person in a public place, probable cause is required. Probable cause means that the officer has enough knowledge or evidence to believe that a crime has been committed and that the person being arrested is the one who committed it. This standard is higher than reasonable suspicion, which merely allows an officer to stop and briefly detain an individual for questioning.

The requirement for probable cause ensures that there is a solid legal foundation for the arrest, which helps protect the rights of the individual and reinforces the accountability of law enforcement officers. Unlike the options that suggest minimal documentation or reliance solely on reasonable suspicion or a warrant, probable cause serves as a crucial safeguard in upholding the principles of justice and civil liberties. Thus, it is the correct answer in this context.
