Which of the following is true about the process of arrest?

The process of arrest is fundamentally guided by the legal requirement of probable cause. This means that law enforcement officers must have a reasonable belief, based on facts and circumstances, that a person has committed, is committing, or will commit a crime. When an officer has probable cause, they are authorized to make an arrest without a warrant.

An arrest warrant is another valid method through which an arrest can be made, serving to provide a pre-approved legal framework for apprehending an individual. However, it is not the sole means of effecting an arrest. Therefore, the correct choice highlights that police officers can legally arrest someone if they have probable cause or a warrant, affirming their authority to act in situations where urgent response is necessary. This balance allows officers to maintain public safety while respecting individual rights under the law.
