In one day, at least 10 schools across the state were forced into lockdown over a school threat. Officials believe the number of threats was not a coincidence. "The first thing is I want to know if it’s real or not. I mean you know? What’s a prank and what’s real," parent Sharon Veasley said. The feds are now investigating what they call swatting, a coordinated campaign when a caller says a school's name, the address, and claims to be a teacher reporting one of their students shot another. The swatting call sent a swift and heavy police presence to Renaissance High School and Huron High School in Ann Arbor. Parents say they are concerned.
