It's an Epidemic!
The radio announcer was droning on about the latest "front" in the drug war, the "epidemic" of crystal meth use. Describing this in terms of an "epidemic" is an interesting strategy: it's the invasion of some alien factor from totally outside our society -- a microbe of some sort -- that has mysteriously chosen this moment to strike. The rising use of crystal meth has nothing to do with anything actually occurring in our society, for instance, the drug war itself. And there's no one behind that curtain.
