Question: An unarmed teen was shot in 2015 by a Wisconsin police officer that drew attention from what group that campaigns against violence and systemic racism towards black people?

<P0-S0> The shooting of Tony Terrell Robinson Jr. occurred on March 6, 2015, in Madison, Wisconsin. <P0-S1>  Robinson, an unarmed 19-year-old man, was fatally shot by 45-year-old Matthew Kenny, a Wisconsin police officer, during an altercation that occurred while Kenny was responding to reports that Robinson was jumping in front of cars and had attempted to strangle someone. <P0-S2>  On May 12, 2015, the shooting was determined to be justified self-defense by the Dane County District Attorney Ismael Ozanne. <P0-S3>  The death was protested by the Black Lives Matter movement; Robinson was African American. <SEP> <P1-S0> The Special Patrol Group (SPG) of the Royal Ulster Constabulary was a tactical reserve of 150 officers which had the role: "to provide backup in civil commotion, to police sensitive areas at times of confrontation, and to show the flag in a disciplined and impressive way to those who wished to break the peace." <P1-S1>  Formerly known as the Police Reserve Force, the name was changed to Special Patrol Group in 1970 following the Hunt Report and the reforming of the Royal Ulster Constabularly to bring it more into line with othe U.K. Police Forces i.e . <P1-S2>  It became an UNARMED POLICE SERVICE , which was temporarily armed due to the continued murderous campaign waged upon the men and women of the service , whether armed or unarmed and whether on or off duty and also to avoid confusion between the defunct more militarised Reserve Force and the newly formed RUC Reserve which was recommended in the Hunt Report and consisted of a large number of part time , trained officers to help with security and relieve the hard pressed regular officers of some of the more mundane duties as well as a small number of full time Reserve Constables who were more fully integrated into the regular service . <P1-S3>  These police reserve officers provided much needed support to the hard pressed regular officers especially in the 1970s when casualties and fatalities among both regular and reserve officers were reaching figures of 2 or 3 officers, on average , being murdered every WEEK . <P1-S4>  The Special Patrol Groups were formed as mobile support units originally based around police stations in Belfast and with a section ( Orange Section ) in Armagh and it required a minimum length of service and a rigorous interview process before an officer could be accepted into the ranks . <P1-S5> These requirements were later dropped most likely due to the need for greater numbers from what was a small pool as the RUC was greatly undermanned to cope with the terrorist campaigns being waged from various so called Loyalist and Republican organizations . <P1-S6>  Officers in the SPG were called upon to deal with major civil unrest as well as numerous , regular bombings , shootings etc sometimes involving multiple bombs in Belfast city centre and other locations on the same day . <P1-S7>  In the 1970s the SPG relied heavily on the calibre of its officers as they were poorly equipped , carrying low power Walther pistols and World War 2 , Sterling sub machine guns to defend themselves against terrorists armed with high velocity weapons such as the American Armalite and M1 Carbines as well as RPG Rocket Launchers , various mortar devices and heavy machine guns . <P1-S8>  They were so disadvantaged as regarded firepower , that , at one stage in the early 70s , members of the Parachute Regiment were assigned to each long wheel base Land Rover to supplement the meagre firepower of 1 or 2 Sterlings in each crew . <P1-S9>  This was a short term exercise as it gave the " wrong " image , not at all in keeping with the aims of the aforementioned Hunt Report . <P1-S10>  Members of the Royal Military Police were brought in , after the disastrous folly of them trying to patrol staunchly Republican areas such as the Bogside and Creggan in Londonderry , unarmed and in unarmoured cars which were painted white ( to the delight of PIRA Snipers ) which resulted in a number of them being shot . <P1-S11>  . <P1-S12>  It was not however until an English Chief Constable , Sir Kenneth Newman , took over that the political correctness was set aside and RUC officers in general and the officers of the Special Patrol Groups in particular , were issued with and trained in the use of more uptodate weapons with which to defend themselves and the law abiding citizens of Northern Ireland . <P1-S13>  Prior to that the men and women in the SPG in particular had scored many sucesses against the terrorists mainly by their courage and alertness , including intercepting bombs , and preventing numerous gun attacks as well as standing up to hundreds of rioters with little or no protective riot gear ( compared to what we see today ) <SEP> <P2-S0> Colin Roach was a 21-year-old black British man who died from a gunshot wound inside the entrance of Stoke Newington police station, in the London Borough of Hackney, on 12 January 1983. <P2-S1>  Amid allegations of a police cover-up, the case became a cause célèbre for civil rights campaigners and black community groups in the United Kingdom. <P2-S2>  Prior to Roach's death, Hackney Black People's Association had been calling for a public inquiry into policing in the area, alleging that there existed a culture of police brutality, wrongful detention of black people, racial harassment, and racially motivated "stopping and searching." <P2-S3>  Ernie Roberts, the MP for Hackney North and Stoke Newington, said that there had been "a complete breakdown of faith and credibility in the police" in the area and the Commission for Racial Equality called for a full inquiry into both the death of Roach and the policing in Hackney generally. <P2-S4>  In June 1983 a coroner's jury returned a majority verdict of suicide. <P2-S5>  INQUEST, the United Kingdom pressure group founded following the death of Blair Peach at the hands of a police officer in April 1979, was highly critical of the coroner's directions to the jury, and said that he had wrongly pointed them towards a verdict of suicide. <SEP> <P3-S0> Black Lives Matter (BLM) is an international activist movement, originating in the African-American community, that campaigns against violence and systemic racism towards black people. <P3-S1>  BLM regularly holds protests against police killings of black people and broader issues of racial profiling, police brutality, and racial inequality in the United States criminal justice system.
