This is wild because it's gotten so easy to track everything. Everyone has a nearly government mandated tracking device shoved up their ass at all times, everything under the sun has a camera on it and your car is phoning home with your sex acts but apparently knowing what every single human is doing every picosecond of the day isn't enough and they need more tanks.

That said, if I had to guess, at least some of the "clearance" in the past was just picking a random black person and stringing them up then going out for doughnuts
