If the police are protected under a clause of "just following orders", then the home addresses shouldn't be shown. Neither should individual policemen be called out. Rather the system is at fault, and the law makers behind it.
If the police are morally at fault, then this extends past their work-life sphere. If you kill and abuse at work and that is considered immoral, you are not simply allowed to go home and claim sanctuary.
In the view of Lulzsec, there are two sides---we the people, and they the State. Revealing the information of the officers to the people is analogous to the FBI keeping records of the names and known addresses of who they consider criminals.
