From what I know there was no way to prevent the Mandalay Bay shooting, and that is true for most of the mass shootings I’ve heard of. Even if people were armed at the concert they would not have been able to stop the shooting, in fact people in rooms around him would have probably been killed accidently. A platoon of armed drones, maybe, like in Bladerunner 2049. We need to stop looking to the government to solve everything and just accept that life sometimes sucks. I’m honestly glad that he shot himself and saved tax payers the additional cost of court and incarceration, think of it as instant justice/punishment. I do think this will affect people going to Vegas, even before this all happened I had decided I don’t want to go to Vegas. No more cheap rooms/buffets/table limits too high for my blood.
