o freedman, free Negro, or mulatto not in the military service of the United States government, and not licensed so to do by the board of police of his or her county, shall keep or carry firearms of any kind, or any ammunition, dirk, or Bowie knife; and, on conviction thereof in the county court, shall be punished by fine, not exceeding $10,
This breaks the 2nd amendment which states that free men are allowed to carry with them ammunition of some sort. However, the "free men" in this situation were not really free, to be considered eligible for this rule.
