The Jerusalem District Court ruled that the security expert and the engineer involved in the tragic lighting rig collapse at Mount Herzl will not be allowed to work in their respective fields for at least 90 days, Jerusalem police announced on Monday. The ruling, which was overseen by Judge Tamar Bezeq Rapaport, can be extended through additional legal procedures. Yitzhak Zuker, the security expert, and Oren Warshavsky, the engineer, are suspected of gross negligence which caused the death of 20-year-old IDF officer Hila Bezaleli. Bezaleli was killed on April 18 when a light fixture collapsed on the event's main stage during preparations for a Jerusalem Independence Day ceremony.
