Heartland Christian Academy’s lawsuit against state officials has gone to trial with school officials claiming the school’s rights were violated by a surprise raid that removed 115 students.

A jury in St. Louis is listening to the testimony. Heartland is a high-discipline private school for troubled students. The students were removed in 2006. Five employees were charged with abuse. But charges against two were later dropped after the other three were acquitted.

The state argues its employees were conducting proper investigations into reports of child abuse.
