Four teachers were led into a room, told to kneel and then were shot with a pellet gun “execution style” and injured during an active shooter training at an Indiana elementary school in January, according to the Indiana State Teachers Association.

The association revealed the violent training tactic, which took place at the Meadowlawn Elementary School in Monticello, while testifying in support of House Bill 1004, which addresses school safety, before the state’s Senate Education Committee on Wednesday.

In an interview with the Indianapolis Star published Thursday, two of the teachers injured during the fake execution said local law enforcement, which was facilitating the training, told them to kneel against a wall in a classroom. They said they were shot with plastic pellets without warning.

The teachers’ injuries in the training including welts and bleeding, the union said. About 30 teachers were involved in the training, according to BuzzFeed.

“They told us, ‘This is what happens if you just cower and do nothing,’” one teacher told IndyStar, which did not name the teachers. “They shot all of us across our backs. I was hit four times. ... It hurt so bad.”
