My point was that Senior Commanders should never be photographed seen touching evidence with bare heads under any circumstances.The forensic team must have taken hours to do their job, and retesting of evidence is always a distinct possibility in high profile murder investigations.
You may well be right, I don't know when the photo was taken, what tests had been done before he touched it, but he clearly understands procedure, he was angered by the forensic guy touching the gun without gloves and told him to put his gloves on, which indicates Van Rensburg has correct procedure in mind. He was at the house for on Feb 14, 15, 16 and 17th.
The door was placed in a body bag and stored in Van Rensburg's office, which he stated he kept locked at all times. On feb 18 when police photographers arrived to take photos of the door, Van Rensburg refused permission for them to take the door out of the bag, insisting that only forensics were allowed to remove it from bag. Van Rensburg also stated that if people wanted faxes (the fax machine was in his locked office), that he did the faxes for them, seems like he protected that door like a Rottweiler to me. He appears very conscientious.
Had he allowed the photographers to take the door out of the bag, before forensics saw it, he would have been accused of stupidity. Had he left the door in a general, accessible corridor in the police station, ditto. Had he lost the keys, or failed to get receipt for their return, ditto. Had he stood and watched the forensic guy handle the gun gloveless, and said nothing, ditto. But he didn't, he seemed aware and protective of the crime scene and evidence.
There comes a point when the police considered that they had finished documenting events and evidence, they couldn't wrap every item in bags and keep the house sealed indefinitely.
On Feb 17 the keys to the house were handed over to Stander by Van Rensburg personally, and from what I remember, Van Rensburg ensured that he got a receipt for the keys.
