And of course that was after he evaded, and after he tried going around a police roadblock, and after he got an agent with his vehicle. Sorry, but any other circumstances and there would be no one denying this was a proper shooting.

Absolutely true.

BUT.... why did they pull him over in the first place, and why was a FBI Drone following him way before he got pulled over ?

Maybe they were operating under the delusion or false information that they wouldn’t be arrested for what they had already done.
They were followed by a helicopter. You’re seeing the FLIR mounted on it. If an FBI negotiator told them they could go to the meeting the FBI would know when it was. Smarter to draw them out than storm in.
