Once I heard a story that the guy who rotated the letter was punished somehow but never found it confirmed. There was a reward offered-sth like 30.000 Euro for person who could help in finding the sign(read: tell the police that his neighboir has recently dug 3 big words in his garden). All of them are said to have already been convicted for robbery and similar acts. Unfortunatelly the sign was cut into three parts.(I pay 1 euro reward for the person who will guess how they cut it
)
PS: Letum was faster than my post...hmm.. never heard that story though I've been to the camp twice(I live sth like 60 km from it)and heard from the historian who shows you all the places the version that is above..so now rly dunno
