Where were these teachers when I was a kid?

Not true. 17 is age of consent, but if the other person is over 19 then it is still statutory rape in La.

This is incorrect. Anyone 17 or older is good for anyone else 17 or older, as long as it is all consensual.

The only reason this teacher got in trouble was that it was apparently with a student. It has nothing to do with his age.
