Ann Lindsey remembers feeling scared and hot when she made the phone call.

It was Aug. 25, 2010. The middle-school teacher was sitting in her car outside Jackson Middle School in Champlin during a 47-minute break from teacher training. Lindsey waited till she was on break and off school property because she worried the call might upset administrators in the Anoka-Hennepin school district.

She was calling an attorney at one of the nation’s leading civil rights groups to report the conditions facing gay, lesbian, bisexual and transgender students in Minnesota’s largest school district.
