Big Brother is Proctoring You

Did you see the story that someone--probably the Education Ministry in Luoyang-- fielded a drone to electronically spy on high school students taking the college entrance exam? It was looking for suspicious signals of unspecified type--presumably cell-phone communications.

My first reaction was "Why didn't they just line the hall walls/roof/floor with aluminum mesh and make a Faraday cage?" But on reflection, "It would get stiflingly hot in there!" And there's no doubt that drones are cooler.

I still have no official word on what the bag limit is for drones in Wisconsin. I'll keep asking.
