The media's accuracy and lack of concern for it being what it is, I'd reserve judgement until the facts are known, if they ever are.
I have responded to alarms as a LEO...
And I've been sent to the wrong location. Twice. Wrong locations which I entered, cleared, and secured prior to being informed of the error.
In response to my queries, there are apparently both technical and human-error reasons which can lead to similar circumstances. In those instances, it is someone's or something's fault, but not the responders.
But maybe it was their fault. Why is an important answer.
Regardless, if they believed they were at the correct location then their actions will be viewed in that paradigm.

As for the dog, the norm in training dictates that dogs get shot before responders get bit. That said, reasonable efforts should, of course, be taken to avoid doing so. Most LEOs would only do so out of perceived immediate danger/need. (Think of how many dogs are successfully negotiated daily vs shot annually.)
As for handcuffing, it is situationally dependent. (Common)
As for naked in the yard, again situationally dependent. (Unusual)
As for the time line, again situationally dependent. (Dependant on too many factors to specualte on)
The last two are the ones, after the reasoning behind the entry of the wrong location, which will be reviewed the most, in my experience. It is also where the plaintiff has the strongest case.
But we know little of what actually transpired, the conditions leading to and following initial contact, cooperation or lack of it, etc.
There's more to the story I'd wager than what's in the press to date.
