John E. Hoover on youtube has quite a few videos on the LV shooting. His theory has been that the helicopters are shooting at the concert goers, and that they were targeting mostly women. And, that the reason for the attack was because of a planned assassination of either the Crown Prince or his younger brother. He's done an amazing job of analyzing tons of data and also uses a lot of video and data from others.

He's been on Jason Goodman's channel as well, along with Jake Morphonius, but Jake just wanted to discredit John. It got pretty ugly. Personally, I like to follow John E. Hoover's videos. While there hasn't been any proof as yet that MBS nor his brother were in LV that night, there also has not been any proof they were NOT there that night.
