McNamara Ground Ops Coffee machine- vigilantiism

A little bit of American history to understand the outrage over the Zimmerman Aquittal.
The 13th, 14th, and 15th Amendments
The 13th, 14th and 15th Amendments to the Constitution outlawed slavery, made it the law of the land that all men could vote, and granted power to the federal government to take action against Ku Klux Klanners and other vigilante thugs who employed lynchings and mob violence against the social progress of Radical Reconstruction. Anti-vigilante laws were adopted in many areas of the country. The abolitionists and their allies who dominated the Congress sent federal troops to the South to defend freed Blacks and their allies.
1877 withdrawal of Federal troops and the end of 40 acres and a mule (Radical Reconstruction)
But with the 1877 withdrawal of federal troops from the South and other counterrevolutionary moves by the Northern rulers, the reactionary forces were given free rein and were ultimately successful in dealing the greatest blows ever inflicted on the working class in the U.S., a body blow that included the imposition of Jim Crow segregation.
Supreme court overturns 1876 New Orleans court conviction of 100 Colfax, Louisiana vigilantes
In 1873 some 150 heavily armed vigilantes attacked and murdered an equal number of out-gunned African-Americans, many members of the city’s militia, who were defending the county courthouse in Colfax, La. The U.S. Attorney in New Orleans indicted nearly 100 of the attackers under the enforcement provisions of the 14th Amendment, affording equal protection of the laws to all. When the case reached the Supreme Court, the justices unanimously overturned the convictions in 1876, ruling the amendment only applied to actions carried out by state governments. This notorious ruling — still the law of the land — was a milestone blow to the fight against vigilantism and racist violence.
