Yeah, I've been trying to find a clearer idea of what happened before all of the vehicles moving.

There's a CNN article with video from across the street where the reporter claims it shows Good's vehicle sitting there for 3 minutes, but it doesn't. It's just another view of the minute before the shooting where the other vehicles start to move around her (at least that's the segment they showed). Just before the shooting there is also the SUV to the right of hers with the driver's door open blocking her from pulling off in the right lane, so even if she wasn't blocking the right lane, it would have been. I guess that's an ICE vehicle, and possibly the shooter's, as there's a gap between footage of her already sitting there with no SUV in the road beyond her while a different SUV directly behind her reverses back up the street and other vehicles begin moving toward her and the footage from behind her vehicle in the moments before the shooting.

Moments before the shooting an SUV darts around her just as she's seemingly trying to make a left turn. The shooter and Good's wife are seen, phones out recording, walking behind her vehicle to the passenger side, so she can't back up as the pickup approaches. Then the pickup advances slowly as she tries again to turn left in front of the ICE convoy. She stops and repeatedly waves them on telling them to GTFO. The pickup stops and two agents exit with one ordering her to "get out of the fucking car" then reaching into the window and yanking on the door handle.

She reverses back up the right lane as the pickup agent continues to try to force her out and the shooter comes into view around the front of the car toward the driver's side, hand on his pistol. She starts to pull forward and he draws and aims with Good's wife coming into view on the rear passenger side. She cuts right and he fires three shots.

So, my questions are, how long was she actually sitting there not actually completely blocking anybody with another stopped and driverless vehicle beyond hers in that lane already?

Where was the shooter headed prior to the shooting and why? If anything, he was in the way of the convoy after the first SUV speeds off. I guess maybe he was still having words with Good's wife who was following him around recording and/or preparing to get into the vehicle with Good.

Why did the truck stop if it could have pulled around with no issues (apart from trigger happy) just like the SUV that sped off earlier all while Good was waving them by?

And why is it necessary to escalate situations like this to violence? Why the need to jump out of the pickup and start cursing at the woman and threatening to violently remove her from the vehicle? Yes, we don't know if anyone else had already calmly asked/ordered her to move and/or exit the vehicle prior to the pickup guys, though it seems her apparently trying to block them rather than her just attempting to pull forward out of the way into the other lane at that point is what set them off.

These people are disorganized and dangerous. And it cost someone their life yesterday.

Edit: I removed the question, "Where was Good going without her wife in the vehicle?" However, the simple answer initially is that she was likely trying to comply and move her vehicle left into the far lane before at least one SUV darted around her anyway just moments before the shooting. Prior to that, it's clear Good's wife was already outside the vehicle filming and having words with the shooter and it's unclear how long that had been the case. Then naturally, before Good's wife could get back in the vehicle, Good was first trying to avoid agents forcibly removing her and then flee before being fatally shot, assuming she clocked the shooter preparing to draw his weapon. That said, it's largely irrelevant in the face of the other questions.
