Hours later, after midnight, officers walked through the front door, rounded up the people inside, and kept them in handcuffs in the front yard for an hour and a half.

The only potential problem, at least from a constitutional standpoint, was that the cops didn't have a search warrant. They got one later, before they seized the boxes of pseudoephedrine, stripped lithium batteries, and other meth-making materials, while the alleged meth cooks waited around in handcuffs, but by then they'd already waltzed through the home uninvited. They neglected to mention this on their warrant application, identifying a confidential informant as their only source of information.
