Final answer:
The least accurate statement about slave patrols is that they promoted equal rights, as their fundamental purpose was to maintain the oppressive system of slavery, which denied rights to enslaved individuals.
Step-by-step explanation:
The statement that is least accurate about slave patrols is c. Promoted equal rights. Slave patrols were established in the American South to enforce slave codes, prevent slave revolts, and maintain order on plantations. Their primary function was to uphold the institution of slavery, which was inherently unequal and denied basic rights and freedoms to enslaved individuals. Therefore, the notion of promoting equal rights is in direct contradiction to the purpose and actions of slave patrols.
Their main purpose was to prevent slave revolts and escape attempts by enslaved people. Slave patrols did not promote equal rights, as they were an integral part of the institution of slavery and served to oppress and control enslaved individuals.
