Has the Namibian Constitution been abandoned?

Just 24 short years after Namibia's independence the Constitution seems to have been abandoned. The conditions in the pretrial detention facility in Okahandja are a grim reminder of the dark ages with their dungeons.

The following facts were related to me by four recent inmates.

The cells:
are totally over filled. Half of the inmates have to sleep in the open, roofless section of cells. There is only one working toilet in the cell, which by the way, is totally open and double serves as the only chair available. There is no washbasin and only a hole in the wall next to the toilet serving as shower.  There are no beds, no chairs, nor a table. Each inmate is supplied with 3-5mm thin "mattress" plus one greasy blanket infested with lice, placed on the bare cement floor. Furthermore the cell(average of 28 inmates) is supplied with 2 bars of soap plus 3 rolls of toilet paper once a week. If inmates don't have friends outside to bring them other necessary toiletries, they just have to do without them. Lights stay on day and night. Inspections are done at various times during the night to intimidate inmates even more,

The Food:
Mornings: 5 slices of brown bread with one teaspoon of either jam or peanut butter on one slice, if available,  + half a cup of coffee/tee mix per inmate. 
Lunch: maize porridge(no sugar,no salt) + a cup of instant soup. 
Dinner: same as lunch. 
Special: Wednesday and Sunday: chicken or meat or fish bones+ cup of juice
Depending on officer on duty, inmates may get a fruit on Wednesdays.
Inmates are supplied with a plastic plate and cup, no cutlery, which have to be pushed through the door bars at mealtimes to be filled.
Meal times depend on the whim of the kitchen personnel.

Once you are inside this facility, you are totally cut off from the outside world and treated like a rabid animal, even though the Constitution guarantees that human dignity may not be violated. Depending on the whim of the controlling officer, inmates may or may not see visitors on Sundays for 5 minutes. 
Pretrial periods vary from 2 months to up to four years.  

Above conditions stand in stark contrast to Article 8 of the Constitution of Namibia, which states:

(1)	The dignity of all persons shall be inviolable.
(2)	(a)	In any judicial proceedings or in other proceedings before any organ of the State, and during the enforcement of a penalty, respect for human dignity shall be guaranteed.
	(b)	No persons shall be subject to torture or to cruel, inhuman or degrading treatment or punishment.

And so one must ask: has the Government of Namibia abandoned the Constitution? Or are our governors just careless in the performance of their duties, employing totally incompetent people in positions of authority?
