Susan is a feminine given name, a form of Susanna, deriving originally from Middle Egyptian "sšn" (lotus flower), first reported on an 11th Dynasty sarcophagus dating from approximately 2000 B.C. However, the Hebrew root for the name for the lily, שושן is derived from the root שוש or ששנ , meaning "to be joyful, bright, or cheerful", which is the basis for the word and name ששון Sasson, meaning "joy of life*". The Persian name for lily is سوسن sousan, susan. The name of Susa, an ancient city of Persia, may be derived from the lilies which abounded in the plain in which it was situated.

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.

Walter "Wally" Pfister (born July 8, 1961) is an Academy Award-winning American cinematographer and director, who is best known for his work on Christopher Nolan's films, including Memento, Insomnia, Batman Begins, The Prestige, The Dark Knight, and Inception. Pfister is also known for his work on director F. Gary Gray's The Italian Job and Bennett Miller's Moneyball. Pfister is currently making his directorial debut on an untitled project through Alcon Entertainment.

Born in Chicago and raised in New York City, Pfister’s grandfather was the city editor of a newspaper in Wisconsin. His father, also known as Wally, was a TV news producer, who began his career with CBS-TV in Chicago in 1955. Later, as an executive at ABC News, the elder Pfister worked with David Brinkley and Peter Jennings, covering political conventions, space flights and the civil rights movement.

When Pfister was about 11, a film company shot scenes for Shamus (1973), featuring Burt Reynolds, in his neighborhood. The boy was fascinated by the crew setting up lights and cameras. Soon afterwards, he began shooting 8 mm home movies and short films. Pfister also emulated his father by shooting slides on Kodachrome film and assembling them into little shows for family and friends.
