Missouri teachers, sex with students off school grounds could be banned. Wait, that was legal?

For Missouri teachers screwing students off school grounds, your dirty, dirty ways could be banned by the Show-Me State real soon.
I guess I should have read the current law because I had no idea that teachers sexing students off school grounds was even legal. But no more, say Missouri lawmakers. They want to make nailing students off school grounds illegal, just like it is on school property and on school buses. Oh, and school board members, your days of screwing students are over, too.
