This story doesn’t make sense, as far as criminal charges go. Sounds like a typical “oh shit, oh dear” reaction.
A substitute teacher at El Campo High School created and starred in a pornographic video using a classroom and a prep room as her stage. She posted the video. This is how the school became aware of the production. The school fired her. Okay, I’ve got not problem with that. No students or staff were participants and apparently did not witness the events directly.
The school is investigating the possibility of filing criminal charges. For what? This assertion was made by the reporter in the attached video. Cooler heads have since prevailed. There are no criminal charges anticipated.
I imagine screenings of the offending videos are available for viewing at the PD and teachers lounge.
