How can a police department of 20 some men and women have issues

Wildwood Crest - How can a police department of 20 some men and women have issues in a town that is so nice? The men and women I have seen working day and night, in the worst weather I can remember, are true troopers! I'm tired of hearing about an "investigation." For what? Can someone please tell us? Obviously no criminal charges have been found, so what's the big deal? Who's behind it? Obviously not the prosecutor's office because they are "overseeing" the police. I sure hope it's not from a disgruntled worker throwing sand in the air, hoping to catch it.
