Opposition to the Civil Rights Movement and "Nation of Laws"

I am trying to answer a question I have.

I am looking for historical facts backed by source documents, not a political discussion and would appreciate that your keep any responses here appropriately focussed on the specific historical question.

Clearly the nation was divided about the civil rights movement (I am particularly interested in the period during the Montgomery Bus Boycott). My hypothesis is that Americans that were opposed to the Civil Rights movement would use the fact that the "Negros" were breaking the law as a big part of the argument.

However, my first attempt at searching for documents that would either support or contradict my hypothesis didn't achieve either. Most of the documents readily available were written by the winning side, and the viewpoint of the opposition is not easily accessed.

But as this was a contentious national issue. I am sure there was a deeply held, well-articulated argument on why the Civil Rights movement was bad.

I would love to have access to well-written editorials from people who were opposed to the civil rights movement.

Can anyone offer insight in the arguments they used to justify their opposition to this movement-- particularly whether the fact that members of the movement were breaking laws was a core theme.
