He can only shoot one gun at once. It's (much) faster to change a mag than to switch guns. Think harder about why he may have had so many. Maybe look into his very unusual non-history and the people around him.
If it's not obvious, officially what happened in Vegas is a coverup.
Do you frequent conspiracy forums, because thats where I've heard that?
The most hilarious scenario is the suggestion that he was actually doing an arms deal with bad guys who were planning on assassinating some Saudi nearby. The arms deal went wrong so they murdered him and to cover that up they shot up a crowd. Which you know, makes more sense than walking away or buying your guns in the desert anywhere within 100 miles around there.
The easier thing to believe is the guy loved guns and decided to kill people. You can't keep up that rate of fire no matter how many mags you've got, that's why he had multiple weapons.
I'd love to hear an explanation that isn't crazy and actually has some evidence behind it, but otherwise Hanlon's Razor and all...
ah, ya, "conspiracy forums" with a "crazy" tossed in. Welp, no point in discussing it then. Case closed. "Hilarious" even... Clearly he needed all those guns for...
"You can't keep up that rate of fire no matter how many mags you've got"
Citation needed. You could make shot timeline with the audio. It's 101 that changing mags is faster than switching guns. I have most if not all of the footage, there is nothing there that makes me suspect he needs more than one gun, I have extensive experience shooting similar weapons.
Did anything remotely interesting happen in SA soon after?
Since you are the authority on what is "crazy" and seem to think someone needs more than one gun to fire that many rounds, there is no way I can have a real discussion, it's "crazy" by def.
