I’m not sure William and Harry’s things would just be lying about in a car. They have security and someone would need to keep an eye on their stuff, even in the VIP section don’t you think? I mean someone could plant a bomb or a hidden camera and they could get in the car. Just doesn’t make sense.
If CH sent someone and they were filming it..and the trunk was opened…you can be sure RPOS are around…no one would get near Harry’s car! It would be watched all the time…security reasons!
