Don't get me wrong, swatting is bad for a bunch of obvious reasons and the swatter is the one with the malicious intent here but if we had a more professional police force (you'd think the swat team, supposedly the most highly trained cops, would have a little more restraint with the trigger finger) it would end this way a lot less often. Cops showing up expecting something where there is nothing should not result in anybody dying, it should result in confused cops and little more. This is very much a two part problem. If the cops didn't have an itchy trigger finger swatting wouldn't lead to outcomes like this.
