Doubt it. The hispanic, probably illegal guy, who was 'shot" in leg, in theory. Has vanished. The whole story is a mess of contradictions. Some may have died, but the story is bogus. I lived in Vegas when that happened. THIS is, NOT SOMETHING president TRUMP is involved in. DEEP STATE, still at it. They want our guns, so we can't defend from their attacks.
Last time something like this event was 'needed' to push for more gun control , some guy supposedly blew up a building with little help, killed over 100, and it made no sense, either. Hearings over the incident the event was supposedly a 'payback' for (Waco) were scheduled, and all it did was tilt the playing field away from gunowners, even though the weapon of choice allegedly was a rental truck full of fertilizer and diesel fuel. Lots of inconsistencies in that situation, too.
The bottom line, though, is whoever pulled those strings has no compunction about killing Americans to get their agenda accomplished--classical ends justify the means stuff. We know who plays by that rulebook...
I doubt Trump would be involved in such, and the Deep State has pulled it off before.
