One of the requirements for obtaining a "no knock" warrant is that there must be exigent circumstances that would make notification of the occupants and securing the premises result in the destruction of evidence or cause great threat to the officers.
Once that warrant is issued, the officers aren't required to re-verify that the exigent circumstances still exist. They aren't allowed to ignore evidence that it doesn't exist, but they don't have to check again. The assumption is that, unless otherwise informed, the exigency continues until the warrant is executed.
It seems to me that, rather than being issued for particular circumstances, in an awful lot of cases, the police just say "drugs" and a no knock warrant is automatically issued. I've seen a lot of numbers tossed around, but it seems pretty safe to figure that several tens of thousands of them are executed every year. That's a LOT.
It just seems to me that in most of the cases the entries end up either dramatically escalating the situation or causing far more damage than is necessary. If I was a police officer, I'd seriously question whether there was a less violent and safer way to apprehend a suspect and secure evidence.
