Context paragraphs:
1981 Toxteth riots: The Toxteth riots of July 1981 were a civil disturbance in Toxteth, inner-city Liverpool, which arose in part from long-standing tensions between the local police and the black community.  They followed the Brixton riots earlier that year.

Metropolitan Borough of Lambeth: Lambeth was a civil parish and metropolitan borough in south London, England.  It was an ancient parish in the county of Surrey.  The parish was included in the area of responsibility of the Metropolitan Board of Works in 1855 and became part of the County of London in 1889.  The parish of Lambeth became a metropolitan borough in 1900, following the London Government Act 1899, with the parish vestry replaced by a borough council.  In 1965 the borough was abolished and its former area became part of the London Borough of Lambeth in Greater London.

Central Communications Command: The Central Communications Command (CCC, also known as Metcall) is the largest Operational Command Unit OCU of London's Metropolitan Police Service.  It sits within Territorial Policing, the business group within the Met that is responsible for Borough Policing and public contact.  It is responsible for receiving emergency and non-emergency public telephony within the Metropolitan Police and between the police and the public & other forces, taking over from a number of smaller communications rooms scattered throughout the service.  The "C3i programme", intended to modernise command and control and combine the MPS's communications into a single department was led by Sir Ian Blair prior to his promotion to Commissioner; the transition to the new system began in 2004 and was completed in December 2007.  The OCU was intended to be known as "Metcall", selected by an internal staff competition, but this name is the registered property of the UK Meteorological Office.  There are three main command-and-control at Hendon, Bow and Lambeth.

Trident Gang Crime Command: Operation Trident, or simply Trident, is a Metropolitan Police Service unit originally set up in 1998 to tackle gun crime and homicide in London's Afro-Caribbean communities following a series of shootings in the London boroughs of Lambeth and Brent.  By 2008 the unit was responsible for investigating "all" non-fatal shootings for "the Metropolitan Police" and in February 2012 the unit's remit was again expanded; the new Trident Gang Crime Command was launched incorporating responsibility for tackling wider gang crime.  In 2013 the unit gave up responsibility for investigating fatal shootings which was taken over by the Homicide and Serious Crime Command.

Metropolitan Police District: The Metropolitan Police District (MPD) is the police area which is policed by the Metropolitan Police Service in London.  It currently consists of the Greater London region, excluding the City of London.  The Metropolitan Police District was created by the Metropolitan Police Act 1829 as an ad hoc area of administration because the built-up area of London spread at the time into many parishes and counties without an established boundary.  The district expanded as the built up area grew and stretched some distance into rural land.  When county police were set up in England the forces of Essex, Hertfordshire, Kent and Surrey did not include those parts of the counties within the MPD and Middlesex did not have a county force.  Similarly, boroughs in the MPD that elsewhere would have been entitled to their own police force did not have them.

1985 Brixton riot: The Brixton riot of 1985 started on 28 September in Lambeth in South London.  It was the second major riot that the area had witnessed in the space of four years, the last in 1981.  It was sparked by the shooting of Dorothy "Cherry" Groce by the Metropolitan Police, while they sought her 21-year-old son Michael Groce in relation to a suspected firearms offence; they believed Michael Groce was hiding in his mother's home.

1933 Palestine riots: The 1933 Palestine riots (Hebrew: מאורעות תרצ"ד‎ ‎ ) (commonly known as Me'oraot Tartsad) were a series of violent riots in Mandatory Palestine, as part of the intercommunal conflict in Mandatory Palestine.  The riots erupted on 28 October 1933, initiated by the Arab Executive Committee.  The riots came as the culmination of Arab resentment at Jewish migration after the rise of Nazi Germany, and at the British Mandate authorities for allegedly facilitating Jewish land purchases.  According to The Sunday Times Perth, the 28 October riots concluded with 20 killed.

Upper Norwood Library: Upper Norwood Joint Library is a public library in Upper Norwood, South London.  It stands on Westow Hill, in Crystal Palace town centre, within the London Borough of Lambeth, but on the edge of the boundary with the London Borough of Croydon.  It is funded by Croydon Council and Lambeth Council, but is not part of either borough's library services.  Instead it has its own policies and procedures, and is managed by a Joint Committee of councillors, four from each borough.  It also has its own membership procedures and circulation system, and does not accept Lambeth or Croydon library membership cards.  It cannot accept or renew returned books or other items from Lambeth or Croydon libraries.

Lambeth slavery case: On 21 November 2013 Metropolitan Police from the Human Trafficking Unit arrested two suspects at a residential address in Lambeth, South London.  A 73-year-old ethnic Indian Singaporean man, Aravindan Balakrishnan, and a 67-year-old Tanzanian woman, his wife, Chanda Pattni, had been investigated for slavery and domestic servitude.  The case centred around the Workers' Institute of Marxism–Leninism–Mao Zedong Thought commune which was led by Balakrishnan.  In the early 1980s after a police raid, Balakrishnan decided to move the group's activities underground.  Balakrishnan's control over his followers intensified and the commune became a prison to his followers.  On 25 October 2013, three women were rescued from the commune.  These were: a 69-year-old Malaysian woman (later revealed to be Aishah Wahab), a 57-year-old Irish woman (Josephine Herivel) and a 30-year-old British woman (Katy Morgan-Davies).  Katy Morgan-Davies was born into the sect and hadn't experienced the outside world until her release.
