as one would expect to happenon a home invasion... No different than if ms13 gang bangers did a no knock home invasion. The cops knew better. They had GOD syndrome. Now hopeflly theey are with God and have found out that THEY are not HIM..
As a famous character in a movie once said, "Stupid is as Stupid does"....
You bust into lots of folks homes unannounced and ya should expect to get shot. That why there are door knockers, door bells, etc...
