They came in with the following information: "a call that someone had an argument with their mother, that the father had been shot in the head and the shooter was holding his mother, brother and sister hostage."
It is my belief that those officers did nothing wrong. It was not a trigger happy cop reacting badly to a traffic stop. It was officers that acted on information that were planted by a malicious individual. The prankster is the one that needs to go to jail for this.

Edit:
Yes, the situation wasn't right. That doesn't mean that the officers on the ground were in the wrong.
There is a more systematic issue going on, you can't put all the blame on the door kickers.
Quoting @matt_wulfeck's comment on another comment thread as he made the same point as I did but with better wording:
"Adrenaline and poor training lead to situations like this.
The department should be held responsible even though it was an individual who made the fatal mistake.
As for the person who called in the swat team, it’s clearly murder."
