What crazy conspiracy theory did everyone forget about overnight?

Vegas concert event shooting. No motive given, brother of the shooter is suddenly whisked away on some kind of CP charges despite owning an AOL-era desktop and nothing else. Throngs of people fired upon and the public gave half a fuck for like a week and moved on, with probably one of the biggest fuck ups in law enforcement and intelligence history getting swept under the kitchen rug in full view of everyone. I’m less concerned with why that Vegas shooter lugged weapons up a hotel tower anymore so much as I wonder aloud what a human life is even worth to the average American.
