there was not much difference between the rules at the early concentration camps. some did not allow smoking; others allowed prisoners to receive food parcels or visits from family members. the rules were still based on existing laws, and the camps were patterned after ordinary prisons. the early camps had penalties like having privileges taken away, or for more severe cases, solitary confinement, a hard bed, not being given food, or being left in solitary confinement in a darkened cell. however, there was no corporal punishment. the early camps were primarily controlled by the sa or the gestapo.
