Why are they tracking it? Shoot it down, open it up and figure out it’s purpose
Once they've assessed it isn't a threat they wait for it to be over an area devoid of people before shooting it down. They also have to follow international laws to identify the aircraft and origin to ensure it wasn't given permission beforehand, but I'm sure the US Airforce stays on top of that.
