This is in Midland Classrooms?

I saw this being shared around Facebook today. It's claiming that this sign is displayed in classrooms here in Midland during the pledge. I honestly have no clue if it's true or not but it seems to be causing quite the upset because it says "It's the Law" and it actually isn't the law as far as I know. What do you guys think?

Personally I think kids need to learn to do what they're told nowadays, and if telling them to stand up for 30 seconds, followed by a few seconds of silence is the worst thing we force kids in this country to do, then we're doing pretty damn good. It seems a lot better than kids in other countries forced to work in sweatshops for crazy long hours and next to no pay. Everyone is entitled to their opinion and I'm sure plenty of people will disagree with mine and that's perfectly fine. Should they say it's the law if it isn't? No. As far as problems in the educational system in the 432, should this be anything we are wasting our time bickering about? Personally, I think parents should take any and all energy they're tempted to put into this issue, and instead put that effort into something that could academically help our kids. I'm not nearly as worried about what they're doing for 30 seconds out of the day as I am about what they're doing for 8 hours a day yet still scoring among the lowest in the state....but that's just me.
