I don't agree, the grenade that was thrown is not part of no-knock, it's because of the extreme violence that gang style criminals are apt to use.
You could have no-knock raids to capture evidence without needing to stun everybody.

Believe it or not, this is the safest way to do "no-knock" for everyone involved. Think about it- if a law-abiding gun owner was woken up to the sound of unknown men breaking down his door and had time to access her weapon, the situation would be much worse for everyone. There have been many instances of this exact thing happening, often resulting in the death of the raid victims and/or police officers. That is why stun grenades are always the first thing that goes into the building during a no-knock raid.
Tell that to this child and to his parents.
