None that I have seen. Frankly, that doesn't pass a smell test.

Room entries are violent and aggressive. You don't quietly walk in and ask people to do anything. You storm the room and scream at everyone to shut the fuck up and don't move or you'll kill them.

The police's competence here is in question, but I doubt they'd fly in the face of procedures that are specifically designed to keep them alive in the most dangerous action you can possibly due as an officer: walk through a door with a gunman on the opposite side.
