This clause was translated into the first 1793 statute which was basically a civil statute that was not well enforced according to the southern states, thus leading to the creation of the 1850 fugitive slave act.

The 1850 act was tougher than the previous one, punishing not only runaway slaves, but also people who harbored or aided slaves in any way, with civil and criminal penalties including up to 6 months imprisonment if caught and prosecuted successfully.

There were many documented cases of people being tortured and imprisoned in south because of helping fugitives.
