'The Waco Examiner' records an episoded that took place during the reconstruction days in the State of Texas:
'Judge Reagan, from Falls County, was arrested on the 5th inst., on the square, and carried to the military camp. The following are the particular: The Judge was suspected of having thrown a brick-bat into the military camp, and upon this suspicion was arrested by the soldiers, and liberated shortly after his arrest. The Judge again appeared on the square armed, and the Sheriff, Mr. Morris, interpreting his demonstration as hostile, arrested him again, and upon which he was taken by the U.S. soldiers in the custody at their camps.'
