The question is why it's necessary to have highly militarized police who respond with overwhelming force at the drop of a hat. Oh wait, that's right, the War on Drugs.
It was fortunate that in this case the target was "a sprawling house in the affluent Atlanta suburb of Johns Creek". Police knock on that house's front door. In other neighborhoods, they simultaneously demolish all doors just before assaulting all the occupants.
Just mentioning this in case anyone had forgotten the purpose of the War on Drugs.
