This flyer has turned up on a couple of college campuses, and it’s probably reasonable to expect there will be more of them:
Obviously this isn’t an official publication of the Department of Homeland Security. Debra Monroe, a professor at Texas State University in San Marcos, reports seeing them on her campus; others have appeared on the East Coast.
That’s a real URL, though.
“We are entering,” says the flyer, “an era of law and order in this country.” I dunno. Ratting people out might be legal, but it hardly seems orderly.
