The thread title is incredibly misleading and also false. When I read the title, I basically thought "Oh silly Texas, what have you done now". But it makes sense why they would charge to teacher, as it is about possible abuse of power.
Furthermore, the teacher is not going to be send to jail, based on the article. It only says that the maximum sentence is 20 years jail time. The article never even states what the expected sentence is. The entire OP is basically misleading and false (expect for the article). But this topic would have been a lot better if everyone would've read the article.
That said, it surprised me how many people here are unaware of sexual misconduct rules or do not regard it as important.
