In August 1955, black teenager Emmett Till was brutally murdered after reportedly flirting with a young white woman while visiting relatives in Mississippi. On November 27, 1955, four days before she would make her stand on the bus, Rosa Parks attended a mass meeting at Dexter Avenue Baptist Church in Montgomery that addressed this case as well as the recent murders of the activists George W. Lee and Lamar Smith. The featured speaker was T. R. M. Howard, a black civil rights leader from Mississippi who headed the Regional Council of Negro Leadership.
The National Commission on Terrorist Attacks Upon the United States (9/11 Commission), chaired by Thomas Kean and Lee H. Hamilton, was formed in late 2002 to prepare a thorough account of the circumstances surrounding the attacks, including preparedness for and the immediate response to the attacks.
On November 27, 2012, a federal judge entered an order granting preliminary approval to a proposed settlement to a class-action lawsuit filed in 2005 by merchants and trade associations against Mastercard and Visa. The suit was filed due to alleged price fixing practices employed by Mastercard and Visa. About one quarter of the named class plaintiffs have decided to opt "out of the settlement". Opponents object to provisions that would bar future lawsuits and even prevent merchants from opting out of significant portions of the proposed settlement.
