"you think it's OK for your unleashed dogs to attack and maul and send to the hospital anyone who happens to place a foot on your property -- then be prepared for the consequences, even if those consequences are "unfair".
My yard is posted with no trespassing and beware of dog signs. The law does not require my dogs to be leashed in my yard and nobody, not even the police, have a "right" to trespass on my property and kill my dogs for defending it. If they were to knock on the door and ask me to restrain my dogs I probably would, but SWAT teams are confused. They believe they are military units and do not operate as civilian police should. They just trespass as they wish and shoot the "enemy" dogs in most cases. IMO SWAT teams are out of control and are used to often for even fairly mundane tasks.
I haven't bothered to research the laws in your state (and I'm sure you haven't either), but if you lived in Florida, not only do the police have a "right" to trespass on your property and kill your dogs, but you can be sued by the police for injuries.
