"Steve had no help". Odd interview with brother of Las Vegas shooter

The brother specifically mentions that he has points to make. One is that Steve acted alone. Toward the end he describes claims Steve had help bringing the guns & ammo up to his room as nonsense.
This is very odd for him to be concerned with whether the official narrative is being believed or not. Why should he care to clarify this point at all? He should just be in grief. Instead he's on a mission to give an extensive, weird, jumbled interview as though it's his job. And he doesn't really like the job, but that's his job. He's not like a grieving relative at all. He's an actor.
How can he claim this was all a shock to him and simultaneously be an expert about whether Steven Paddock acted alone? Very Odd.

It's very obvious after what he started to say which was Army Steve was an Army and then he makes reference to the Armed Forces
