The following comment by Carl Rasmussen is being elevated to a more prominent place here.
The “tombs” above the pool of Siloam are now labeled as “Children’s Cemetary!” Yes, something “fishy” is going on!
Leen Ritmeyer followed up on the subject here, and with several photos taken less than a month ago by his son Nathaniel here. It seems clear from some of the photos that the stones are not attached to any tomb. In fact there are no typical tombs at the site above the Pool of Siloam.
The final photo was taken 29 May 2009 when no tombs were visible.
