RH could well have intended turning the music down or even off until he saw the opportunity to confiscate the gun and ammo. He had a history of discussion with deer hunters in other camps in 2020 about storing guns and ammo safely and sharing the trgic death of his male relative in a deer shooting accident, which has been detailed in numerous media articles IMO and I have no doubt upon seeing the gun and ammo in a car with all doors open as detailed by GL, RH then made an instant decision to confiscate these items. RH had already spoken to GL about why he was using the drone and that had included using it at Bucks Camp for about 10 seconds when GL returned, and that he had taken footage of GL whilst he was allegedly hunting and RH had wrongly accused him of hunting illegally near Bucks Camp when GL stated he was merely making his way back to camp. RH started his radio convo at 6pm and it finished at 6.40 with no alarm noted by participants in convo.GL told detectives he was heading back to camp to have dinner.
After confiscating the gun and ammo RH told GL he intended taking the drone footage, gun and ammo to police. At some stage just after confiscating the items RH also let off 2 shots which would have then supported another detail that RH had said to GL during their conversation, that RH had said he would tell police that GL had earlier fired a shot through the campsite. So firing off the two shots RH was gaining evidence to support his future police report.
This detail has been in numerous media reports and is also in the interview video. IMO
