Answer:The law you are referring to is the Fugitive Slave Act of 1850. This law was part of the Compromise of 1850 and required that escaped slaves be returned to their owners, even if they had reached free states. It was highly controversial and contributed to tensions between the North and South in the lead-up to the American Civil War. Richard Henry Dana protested the law's application in the case of Anthony Burns, a fugitive slave whose capture and trial in Boston sparked outrage and opposition among abolitionists.
