The early, temporary concentration camps, such as Kemna concentration camp, did not have unified, coordinated regulations, but rather drew their Lagerordnung from regulations then in use at various police departments and prisons run by the justice system.[* 1] Differences were nonetheless minor. Some banned smoking, others allowed prisoners to receive food parcels or visits from family members. The regulations were still based on existing law and the camps were patterned after ordinary detention centers.
