I published this video above 1.5 years ago.

Carnegie Mellon researchers appear to have confirmed IAMJOHNCULLEN's findings, 1.5 years later.
Alex Hauptman's team built the Video Event Reconstruction & Analysis system (VERA) as a tool to help law enforcement reconstruct shootings.
By inputting videos captured by multiple cell-phones, VERA is able to determine the range and bearing of the original shots that were fired and recorded.
Funded by SITU Research, NIST, the OAK Foundation, and the MacArthur Foundation, the team hopes their software will help solve mass shooting crimes.
Interestingly, IAMJOHNCULLEN published similar findings 1.5 years ago at the John E Hoover channel with the video linked above. Unlike Carengie Mellon, IAMJOHNCULLEN publishes his findings in detail, demonstrating the range to the shooter from the first 3 shots could not have been coming from Mandalay Bay. In fact, IAMJOHNCULLEN demonstrates that the shooter was 95 meters closer than Mandalay Bay, making it physically impossible for the first 3 shots to have originated from the hotel.
Carnegie Mellon researchers, suffering from confirmation bias, and a lack of exposure to real evidence, have not yet realized that their VERA system shows that Paddock was NOT the lone gunman.
