It's symbolism 101. Nobody was buying J6 as an insurrection because of how peaceful it was, so they wanted to draw an association between j6 and more violence. Solution? Provoke a riot in a less stable population and insert symbols that American idiots will immediately connect with J6 in their minds.
Honestly I've been uneasy about all this Brazil shit from the start, because it's an entirely different country with a very different population. If we internalize what's happening in Brazil as being a mirror of what we're doing, then we can be led around by the deep state provoking violence there (since they've lost their ability to manipulate us directly).
