What do these quotes mean and who said them?

Question

1) We regard them as now being licensed to continue their dark and bloody deeds under cover of the dark night.

2)In every instance... the most uncomfortable, uncleanest, and unsafest places.

3)Our Constitution is color blind, and neither knows not tolerates classes among citizens. In respect of civil rights, all citizens are equal before the law.

Answer 1

OK...one answer to fit all...(Go to a completely irrelevant web site and ask a totally irrelevant question)....

Answer 2

The first one is from an appeal to Congress by a group of Kentucky African-Americans to do something about the Ku Klux Klan, meaning they were upset about the lack of legislation being enacted against Klan members. Number Two is from The Freedman's Case in Equity by George Washington Cable, calling upon the Southern states to give full citizen privileges to the recently freed slaves. The third one is an excerpt from John Marshall Harlan, the only dissenter in the case of Plessy v. Ferguson. He is arguing against segregation--he says "separate but equal" will never work.
