Goin' back to Dallas, take my razor and my gun
If there are people lookin' for trouble, sure gonna give 'em some
I load up my revolver, sharpen up my knife
Some redneck messin' with me man, I'm bound to have his life
Down to Dallas, take my razor and my gun
Man, people there lookin' for trouble, sure gonna give 'em some
"Dallas" Johnny Winter
American segregation wasn't just the attempted physical separation of blacks from whites. It was the zealously enforced rule that black people were inferior and had no right to contradict whites, talk back to whites, displease whites, complain about being cheated by whites, testify against whites or do anything that would set their will against any white person, regardless of age, gender, status, right or wrong.To do otherwise would be to be considered "uppity". And to be considered uppity meant that a black person ran the high risk of assault or worse by local outraged whites, often with the tacit assistance or open cooperation of law enforcement. Supposedly the changes which took place in the 1950s and 1960s put an end to that sort of foolishness. But unfortunately racism doesn't just go away because the law changes. There are still a lot of white people who really do hate black people.
And when that hate is combined with a badge and a gun, bad things can happen. Recently in Texas (and why am I not surprised about this) a white police chief and his friends behaved as if this were 1917 and not 2017.
