Has it been determined,as fact, the denim on the floor were Reevas, other than Oscars version that they are? I may be wrong. But they look suspiciously like men's and as Oscar liked to store his legs in the trousers, if he was in a super hurry trying to get his legs on and pulled them through, his socks would have pulled off and reason for him to add he had to put his socks on as well. This fits with him having no legs in his acts of intimidation and gun fire, then trot off to get his legs phones etc. He also had little blood on the base of his socks in photos yet we have been told they had been taken in the garage?
As we also still have no explanation to 'other' pants. Not neatly out the window.
I don't think the jeans were his as the PT would definitely have picked up on that by now. I suspect Reeva's family faces when they saw them was because they were actually outside in.
