Why respond to someone who is so painfully unaware as to call themselves "Adam Smith" - well because he proves the point. In Fox News style he doesn't check the sources, and then he somehow imagines... exactly what on each side of that 'thin blue line'? Frodo on one side and Bonnie and Clyde on the other?
The "thin blue line" was a translation from the British "thin red line" - with white and might England on one side and the colonial "other" over there. Then it became the white US Army on one side and the colonial "other" - the Filipinos - over there. Then it was applied to Harlem and Bedford Stuyvesant. Then it was applied to Watts.
