I'm seeing people mistakenly claim the gun photo was posted before today, but its just how Google sometimes dates images based on the original date of the thread its posted in, not when it was posted. The photo was posted an hour ago in this 5 day old thread

We’ve placed the available videos of the shooting of Alex Pretti by federal agents in Minneapolis today into the same synchronised timeline and are continuing to analyse further.
