THE HAPPENING WORLD: The United States Army Has a “Chief Diversity Officer”

“We'll have to postpone the amphibious assault. The troops are not sufficiently diverse, and some are suspected of extremism!”

Here is more, if you can take it, from the official army.mil Web site: “Army aggressively working to eliminate extremism, says chief diversity officer”. A quote:

According to the Office of the Provost Marshal General, suspicious behavior or actions of a person, or group of people, should be reported. There are numerous means of reporting: the chain of command, local law enforcement, iSALUTE, and the Insider Threat Hub, among others. If the actions of the person or group are life threatening, call emergency responders and/or 911.

Are there awards for particularly prolific informers?

As I've said before, “Superpower, shmuperpower: one little tap and the whole thing collapses.”
