You Think the House was "Disorderly" Before? Just Wait Until SWAT Gets Done with It

I'm already growing calloused to this never-ending parade of isolated incidences, so I'm going to start at the most important problem I found in this article, and that is:

What in the name of Poseidon's wet wedding tackle does the charge "disorderly house" mean?!?

CEDAR RAPIDS – Police in SWAT gear busted through a door and searched a Cedar Rapids home for drugs Thursday morning, but came up empty.

At least 12 officers surprised the tenants at 1135 33rdSt. NE when they arrived around 7 a.m. with a narcotics search warrant. Sgt. Cristy Hamblin, a police spokeswoman, later confirmed that nothing was seized from the house.

No one was taken to jail, but the tenants of the house, Justin Davis, 28, and his girlfriend, Erica Lewis, 26, were charged with disorderly house and signed a promise to appear in court, police said.[emphasis mine]

The end of the article goes on to explain that "'[d]isorderly house' is [a city ordinance] described as a building or room where someone 'resorted to for' illegal activity involving drugs, alcohol, gambling or prostitution..."

So, I ask again, what in the name of Pinocchio's splintered sphincter is "disorderly house", besides a consolation prize for homeowners who didn't satisfactorily play their role in the local police's action drama?
