What are the legal grounds for arrest in Georgia?

The correct choice highlights that the legal grounds for arrest in Georgia are based on both probable cause and reasonable suspicion. Probable cause refers to the reasonable belief that a crime has been or is being committed, which is a crucial standard that law enforcement must meet before making an arrest. This encompasses evidence that would lead a reasonable person to believe that a suspect has committed an offense.

In addition to probable cause, reasonable suspicion allows officers to briefly stop and question a person based on specific, articulable facts that suggest criminal activity may be afoot. This standard is a lower threshold than probable cause and is especially relevant in situations where officers are assessing potential threats or suspicious behavior without making a full arrest.

The other options do not capture the essential legal basis for arrests in the state. For instance, while public complaints and eyewitness accounts can provide valuable information to law enforcement, they do not on their own constitute the legal standards needed for an arrest. Searches and subpoenas are procedural tools but do not relate specifically to the legal grounds for arresting individuals suspected of criminal activity. Thus, the combination of probable cause and reasonable suspicion effectively summarizes the legal framework governing arrests in Georgia.
