It’s more plausible they’ve been leaving gaps in his security perimeter for a long time hoping someone would take advantage of it. Trump needs his own security consultant to check every venue and its security going forward...and hire a dozen or so bodyguards...I also expect every MAGA supporter to be on full alert at any event going forward.
Yeah, that would have to be the case for this kid to not have been “delivered” to this exact event. The one problem with your theory is that Butler seemed to be an exception by many accounts. But maybe that’s just people’s reaction given that something happened here, that’s plausible, too. Maybe all along these events have just been inadequately secured.
We should be looking back at past rallies. Were they secured properly? Would be a good question to answer.
