And as somebody else said, no telling how many GOT THROUGH. These were just he ones caught!

My guess is that for at least every 1 caught, 10 have gotten through, at the very least, so you could conceivably have 40 active North Korean agents in the United States (outside of those attached to the DPRK Mission in the UN in New York) carrying out espionage or possibly sabotage or waiting for orders to engage in terrorism. My general estimate would be a higher figure. Either way, as a nation, we are porous. The DPRK are not.
