It’s been memory holed for two reasons I believe:
1. The coverage helped Trump and the MSM could not allow that.
2. The attempt was an inside job, the MSM knows it, and MSM has to protect those involved.
I agree with both your points. To point 1), they even admitted that they were suppressing the iconic fist-thrust photo since it so clearly helped Trump.
I believe you’re right on both counts. This ain’t 1963. We The People aren’t easily fooled anymore;our distrust of government has grown over the decades, plus we have common access to technology that didn’t exist 60 years ago. We can determine for ourselves whether or not someone is gaslighting us. We CAN be more in control of our own destinies, but first we have to break the Big Government hold on all of us.
Also, if they get people to forget about this attempt, it will be easier to convince them the next one was just an unfortunate combination of miscues. Nothing intentional. Remember, they’ve already warned Trump they can’t protect him at outdoor rallies.
