I don't do links still.
January 6th was broadcast live here. It was real. The FBI does not have tens of thousands of agents, and they have even far far far far fewer neckbeards.
Once time during my Punk Rock days in the 1980s, in front of CBGB's for a weekend matinee (daytime, obviously), these three guys showed up, tall, good looking, dressed with the usual Punk uniform. I couldn't stop looking at them, because something seemed unusual. They were too perfect. They definitely stood out, so I would have recognized them if they were there before. Their clothes, their accoutrements - everything was too perfect. Nicely clipped, pristine, everything clean. All three of them.
Normally you get into the scene, you add things little by little, but over time your boots get dirty, the MC jacket gets worn around the edges, the studed wristband isn't so shiny, the bandana gets a little tattered... But everything on these guys look like it was carefully crafted before they got there that day. They stood by the side of the crowd there, chatting with themselves, looking. And eventually one of them said something to the others, and they turned and walked back in the direction from which they came. This was before any of the bands even started playing. I never saw them again.
Anywho, the point is, plants or just some newbs trying to fit in stick out. I can grow a foot long beard and wear a flannel shirt with the hunting vest or whatever the heck they wear, but if I was in that crowd I would still stick out. Like that clip as some demonstration where they added the undercover FBI guys because they were too obvious. Remember, they want to fit in, but they also have to be able to recognize each other. But it's also a bit difficult for someone to emulate looking like they just walked out of Duck Dynasty.
There's people who claim 9/11 was a hoax. The view out my window said otherwise. First two days the dark slate smoke arched towards Brooklyn, the third day it turned towards New Jersey (buildings a couple blocks down had always blocked my view of the Twin Towers). Then gradually it started to get lighter and lighter, till the smoke was almost white weeks late. I didn't go downtown till 2004, and I'm pretty sure that was a pretty darn big pit where those buildings were when I went past there. Maybe it was a hoax. Maybe me and 8.5 millions were in on it. Maybe.
