ATLANTA – In today’s educational environment, it usually takes indisputable evidence like video to get a school to take action against an abuser.

A teacher in the Atlanta Public Schools district suspected something was wrong in her colleagues’ classroom so she decided to set up a camera to record the learning environment.

What she captured was hard evidence of two teachers’ aides berating and slapping special needs students.

She turned over just four days of footage, according to the Daily News, and one of the women was arrested and charged with battery and child cruelty.

“I haven’t been the same. I haven’t been able to return to the work environment,” the teacher says.

The aides are identified as Alger Coleman and Keisha Smith.

The disturbing video shows “Coleman smack a boy in the head after he spilled some water, slapping the child right out of his chair. After the boy gets back up, he’s put in a vicious chokehold from behind, then slapped again,” reports the Daily News.

“It’s really hard because I feel like I can’t trust no one. I feel like Atlanta public schools failed me,” a mother tells NBC 11.
