Italians (Italian: italiani) are an ethnic group native of Southern Europe that share a common Italian culture, ancestry and speak the Italian language as a mother tongue. Within Italy, Italians are defined by citizenship, regardless of ancestry or country of residence (though the principle of jus sanguinis is used extensively and arguably more favorably in the Italian nationality law), and are distinguished from people of Italian descent and, historically, from ethnic Italians living in the unredeemed territories adjacent to the Italian Peninsula.
In 2012, in addition to the 60 million Italians in Italy and 3,000 in San Marino, Italian-speaking, autonomous groups are found in neighboring countries: about 500,000 in Switzerland, a large, but undefined population in France (Nice, Corsica), and smaller groups in Slovenia and Croatia, primarily in Istria. If regarded as an ethnic group, they constitute one of the world's largest.
Because of wide-ranging and long-lasting diaspora, about 4 and half million Italian citizens and over 70 million people of full or part Italian ancestry live outside of Italy, most notably in South America, North America, Australia and parts of Europe.
A police officer (also known as a policeman or policewoman, and constable in some forces, particularly in the United Kingdom and other Commonwealth nations) is a warranted employee of a police force. In the United States, "officer" is the formal name of the lowest police rank; in many other countries "officer" is a generic term not specifying a particular rank, and the lowest rank is often "constable". Police officers are generally charged with the apprehension of criminals and the prevention and detection of crime, and the maintenance of public order. Police officers may be sworn to an oath, and have the power to arrest people and detain them for a limited time, along with other duties and powers.
Some police officers may also be trained in special duties, such as counter-terrorism, surveillance, child protection, VIP protection, and investigation techniques into major crime, including fraud, rape, murder and drug trafficking.
Responsibilities of a police officer are varied, and may differ greatly from within one political context to another. Typical duties relate to keeping the peace, law enforcement, protection of people and property, and the investigation of crimes. Officers are expected to respond to a variety of situations that may arise while they are on duty. Rules and guidelines dictate how an officer should behave within the community, and in many contexts restrictions are placed on what the uniformed officer wears. In some countries, rules and procedures dictate that a police officer is obliged to intervene in a criminal incident, even if they are off-duty. Police officers in nearly all countries retain their lawful powers, while off duty.
The English (from Old English: Englisc) are a nation and ethnic group native to England, who speak English. The English identity is of early mediaeval origin, when they were known in Old English as the Anglecynn. England is now a country of the United Kingdom, and the majority of English people in England are British Citizens. Their ethnonym is derived from the Angles, a Germanic people originally from Northern Germany who migrated to Britain.
Historically, the English population is descended from several genetically similar peoples—the earlier Britons (or Brythons), the Germanic tribes that settled in the area, including Angles, Saxons, and Jutes, collectively known as the Anglo-Saxons, who founded what was to become England (from the Old English Englaland), and the later Danes, Normans and other groups. Following the Act of Union in 1707, in which the Kingdom of England became part of the Kingdom of Great Britain, English customs and identity became closely aligned with British customs and identity.
