[ Politics ] Open Question : Can you believe that our government has found “no motive” for the Las Vegas shooter’s murder spree?

Sorry, but I ALWAYS follow up on these mass shootings and the criminal who did them. I have a need to know his history. I CANNOT ACCEPT that someone so heavily armed and such a well planned and staged series of murders had absolutely no motive whatsoever in doing this. As though this was just circumstance or a joke.
