While I do yeild to your experience in that field- I think the question most are posing here, and again, we don't know the full story- but if all parties occupying the home are stating that the police were called in error, there was no reasonable grounds for anyone to suspect a DV was taking place, then what right do the cops have to illegally kick the door down and enter the home? To the best of my knowledge, none. Which would then lead me to believe that the moment they kicked my door down, all officers involved were violating my rights and subject to litigious action against the individuals and the department (unless they posed a direct threat to my/family's life, at which point it would be handled on a case by case basis).
ETA: Of course that's only hypothetically speaking if they came to my house in error on a DV call. In this particular case, no idea what happened prior to the filming, but it would appear, at face value, that no DV was taking place and without a warrant or probable cause, LEOs cannot enter your home without your permission, unless exigent circumstances exist- which I saw no cause for them to kick the door down- but again, I didn't see much in that video to sway either way.
