re: Has any official said “we ain’t found no motive yet” regarding Vegas?

I have no idea what you're even trying to assert. It honestly seems like youre trolling but maybe not.

A lone crazy gunman would literally be the hardest thing to confirm, as it would have little to no evidence to support it outside his internal monologue. It's the one possibility that would make the investigation take longer than any other motive. Instead, you feel like the lack of evidence points to him just being a crazy loaner? Help me understand this.

I feel like I'm explaining to someone that water is wet.
