I would say that the daughter is now at great risk. I'd go out and acquire six of the best attack dogs possible...all trained to attack and kill anyone in a police uniform. I'd then turn around and let the cops know that should they ever come back to my neighborhood...unannounced...as fast as the cop might think he can shoot...one of those six will get to him...and will go for the throat.
Of course, I could put up posters around town of policemen and the caption of "dog killers protect your neighborhood" and accomplish alot with that as well...and avoid paying for six dogs.
Your proposed solution shows malicious intent toward the police officers. That would set the family up for prison time. In the case discussed in this thread, the cops were on an investigation of a "non specific gun complaint". That sort of mischief happens all the time. Angy ex-spouses and girlfriends/boyfriends make false reports to cause people trouble. Aside from killing the dog, the investigation found the complaint groundless. The person filing the complaint needs to be investigated for filing a false report.
