In Texas, if you're a School Teacher, then there's a law against sexual relations with students, regardless of their age. So for Texas school teachers, there is no "age" defense, as some students have reached the "age of consent", so for clergy and school teachers... there are extra prohibitions.

But all of the teachers are well aware of the law.

Just like career criminals and gang members.... they full well know the law, and break it anyway. They probably know the law better than most.... but, they break it anyway.
