I largely agree about them not being able to weed out any Trump supporters in that 25,000, but they don't really need to.
They've probably handpicked them most important ones and I know that they replaced the Secret Service people recently.
There could be a lone lunatic in there somewhere, but they just need to keep him at a respectable distance.
As long as he doesn't get a clear shot at Biden or anyone else important, then he probably won't even do anything.
You'd hope that they've got enough expertise in there to prevent anything explosive getting rigged up.
As for Ashli Babbitt, she would've been flagged instantly if they'd have done any checks in the last couple of years.
She appears to have jumped on the Q/Trump train after leaving the air force, as her social media posts weren't as mental when she was in it.
The last six months or so were particularly bad, apparently.
The problem is that there'll be fruitcakes out there that either don't post on social media or are sensible enough to do it anonymously.
Will one get into a position to do anything? We're about to find out!
