Constable
Summary
A constable is a person holding a particular office, most commonly in criminal law enforcement. The office of constable can vary significantly in different jurisdictions. A constable is commonly the rank of an officer within the police. Other people may be granted powers of a constable without holding this title.
Historically, the title comes from the Latin comes stabuli (attendant to the stables, literally count of the stable) and originated from the Roman Empire; originally, the constable was the officer responsible for keeping the horses of a lord or monarch.
The title was imported to the monarchies of medieval Europe, and in many countries developed into a high military rank and great officer of State (e.g. the Constable of France, in French Connétable de France, who was the commander-in-chief of all royal armed forces (second to the king) until prime minister Cardinal Richelieu abolished the charge in 1627).
Most constables in modern jurisdictions are law enforcement officers. In the United Kingdom, the Commonwealth of Nations and some Continental European countries, a constable is the lowest rank of police officer (it is also, when preceded by the term sworn, used to describe any police officer with arrest and other powers), while in the United States a constable is generally an elected peace officer with lesser jurisdiction than a sheriff; however, in the Channel Islands a constable is an elected office-holder at the parish level.
Historically, a constable could also refer to a castellan, the officer charged with the defence of a castle. Even today, there is a Constable of the Tower of London.
An equivalent position is that of marshal, which derives from Old High German marah (horse) and schalh (servant), and originally meant "stable keeper", which has a similar etymology.
Australian police ranks
In Australia, as in the United Kingdom, constable is the lowest rank in most police services. It is often categorised into the following (from lowest to highest): probationary constable; constable; constable first class; senior constable; leading senior constable.

Search warrant
A search warrant is a court order that a magistrate or judge issues to authorize law enforcement officers to conduct a search of a person, location, or vehicle for evidence of a crime and to confiscate any evidence they find. In most countries, a search warrant cannot be issued in aid of civil process. Jurisdictions that respect the rule of law and a right to privacy constrain police powers, and typically require search warrants or an equivalent procedure for searches police conducted in the course of a criminal investigation.
Law enforcement officer
A law enforcement officer (LEO), or peace officer in North American English, is a public-sector or private-sector employee whose duties primarily involve the enforcement of laws, protecting life & property, keeping the peace, and other public safety related duties. Law enforcement officers are designated certain powers & authority by law to allow them to carry out their responsibilities. Modern legal codes use the term peace officer (or in some jurisdictions, law enforcement officer) to include every person vested by the legislating state with law enforcement authority.
