The word "muscle" in the text implies that Bull Connor, after paying special attention to the Segregation Ordinances, had the legal power, authority, or strength to act as he wished. The word muscle is used as a metaphor, since it means another thing, and gives the reader the image of a bully.
The word "muscle" helps readers connect with an image of Bull Connor as a bully who pushes others around. The author could have used a word like "power," but that would not connect with the reader in the same way. "Muscle" helps readers imagine him using his power to hurt others, which creates a negative tone.
