High School Root Beer Party Raided

OK. So it makes for an amusing story about the cops bursting into a party full of teenagers drinking root beer, but, where was the reasonable suspicion or probable cause for the search and at least temporary seizures of every single person in the house?

Cars lining the street. A house full of young people. A keg and drinking games inside. Police thought they had an underage boozing party on their hands.

But though they made dozens of teens take breath tests, none tested positive for alcohol. That's because the keg contained root beer.

90 breath tests. No alcohol.
