Did they announce that they were the police with a warrant? I''ll bet she could have opened the door in less than two minutes.
Amendment IV
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
Modern times, the Constitution is a living, breathing document. The fact that it is on life support right now and some are only too happy to pull the plug is irrelevant. Whatever it takes to bust those foul criminals with a 1/4 ounce of weed.
No knock warrant which means they break down the door and/or windows and charge in. There's reference in the article to supposed cameras on the premises which the cops used to justify the no knock warrant.
