They figure it out. Look up about Mena, Arkansas. Guy had his own plane and was working for a cartel. I think he eventually got caught and did a deal. Threw the cartel under the bus for some kind of bargain. The cartel killed him eventually. California has tunnels from Mexico, I guess. They even showed it on that show Weeds, HBO. There are many ways they figure this out. I don't know the air ports don't seem to be to smart about these things. I mean we hear stories and see the news sometimes. But the last couple times I flew. I had some large bags of a powdered vitamin. It was just a plain ziplock. It was in my carry on. They didn't question it or check it. They would have realized it was just a vitamin, but they did not even pay attention to it. So, you do the math on that.
