In auditing you look for red flags. They are weird bits in the data that suggest something shifty is going on. You flag those weird things so you can delve into them further. One flag does not necessarily mean there is fraud. Weird things and honest mistakes happen. A few flags mean

I am more offended by how ham fisted, clumsy, and audacious the fraud to elect him is than the idea of Joe Biden being president. I think Joe Biden is a corrupt idiot, however, I think America would survive him like we’ve survived previous idiot administrations. However, what is potentially fatal for America is half the populace believing that their elections are hopelessly rigged and they’re eternally fucked. And now, however this shakes out in court, that’s exactly what half the country is going to think.
People are pissed off, and rightfully so
I can say without hesitation that skullduggery is afoot, and if an actual real investigation happens they will be able to prove it. These people were just to blatantly confident in their schemes.
