Your reasoning is a little dubious there. I should not favor suing the department when I can find no legal theory under which they should be liable. And in this case it was an individual officer mistake that directly did no harm, and was corrected as soon as it came to the department's attention. I'm not going to find anything in police training or general behavior that fits with this mistake being a general pattern that is endemic to the department. I see no damages or legal relief that makes sense here. Arguing about what good might come from the department losing said lawsuit is like debating how convenient it might be if pigs could fly. The whole conversation is based on something that isn't going to happen, and therefore isn't a real possibility. And any attempt to go from discussion to reality by actually filing said lawsuit is a waste of effort.
