Durban - Bulletproof state vehicles will be damaged if they stand out in the sun, a police official explained to journalists while giving them a tour of the garages at Nkandla on Sunday.General Mondli Bethuel Zuma said an internal police memorandum on Nkandla, signed by senior superintendent LF Linde, had an attachment which showed that garages were also requested.“They are used for state vehicles. If a bulletproof vehicle stays in the sun for too long, the windows get damaged. Each window is more than R200 000. If we change four, then that's more than a million [rand],” he said.“All the vehicles that park here, this is where the president's vehicles park. This was requested by the police. There is a debate about the garages, this all belongs to the state," he said, adding that there was still a barrier line or fence between the homestead and the state-owned infrastructure.Journalists were also shown the kraal and animal culvert. Zuma said there were goats and other animals running around on Sunday morning because motion detectors were not in place.“There is an allegation that the family kraal has been moved but that's not true. The animals were moved so that they do not disturb the motion detectors,” he said.“If the work was not stopped, we would have had motion beams to detect people moving in and out of the homestead. The motion detectors at the moment are lying on the floor because they have not been installed."Zuma said the animals were moved because they would send false signals to the control centre.“There is a culvert at the bottom because the animals must avoid the security infrastructure. This will trigger false alarms. There should be no interface between the animals and the security.”The media was allowed into President Jacob Zuma's Nkandla homestead in KwaZulu-Natal on Sunday for an official tour. This visit comes after the SA National Editors' Forum said it was disappointed by the limited access journalists had during a parliamentary committee oversight visit to Zuma's home on Wednesday.
