"Completely at random," this particular drone just happens to rise up and focus directly on the area where the shooting occurred, before it was even notable that Rittenhouse was fleeing Rosenbaum.
Timestamp 0:45.
Slow down to 0.25x speed (utilize "playback speed" option after clicking the 'settings' gear).
Watch through 0:50.
See the flash from the handgun in the top right corner of the screen?
Drone operator didn't bother to investigate a gunshot recorded by the camera (active shooter situation ignored). Focused dead-center on where Rittenhouse was running instead. Dead fucking center, captures Rittenhouse shoot Rosenbaum, and drop him.
That's pretty amazing.
Your guess has as much merit as anyone else's but 12 months from now is too far away.
That's one thing I'd be very happy to be wrong about, would love for it to happen sooner. With as a caveat, all the necessary avenues that might allow perps to escape justice being shut down before the main event.
Essentially just as we have seen with the careful and measured way Durham is tracking his way up the org chart of crime figures taking them down in the necessary sequence to not give out escape opportunities for the big fish.
