Color-blind underaged drinkability?

Thanks to Eric for directing my attention to this story from earlier in the year.

Seeing red
According to the law, Dustin Zebro wasn't doing anything wrong. But so far, the 18-year-old senior's school doesn't see it that way. The Wasau, Wis., teenager staged a party on March 1 at his home that every parent dreads: hordes of teens, drinking games, and a keg. Police were called to the party and arrived to find dozens of high-schoolers drinking from red plastic cups. But a funny thing happened: Nobody scattered, and when police began administering breathalyzer tests—90 in all—every kid passed. That's when police searched the keg to discover not beer, but a quarter barrel of 1919 Classic American Draft Root Beer. Zebro said his root beer party was designed to prove kids could have fun without alcohol, but also to make fun of the school for what he assumed would happen next. As soon as pictures of the teens at the party drinking from red cups hit Facebook, school administrators handed down extracurricular suspensions to Zebro and others. "They assumed there was beer in the cups," Zebro said.

The moral of the story?

Don’t drink root beer out of plastic cups, either. Had the kids been using glasses, and the otherwise paranoid school administrators gazing at the photos on Facebook could see dark liquid, they’d have properly smelled a rat – all underaged kids drink yellow beer, right?

In turn, this would have permitted the kids to drink Porter and not get busted.

You have to think these things through. That's what education's all about, anyway.
