The local police force has given a man a job of becoming a serial murderer. This may seem counter productive, but it certainly works out for the good guys. You see, the police give their serial murderer a list of individual to stalk threaten, and kill if necessary. It's a manufactured problem the police have full control over.
Next, after some killings become public, police start going to families and individuals on the kill list and giving them an ultimatum. Give full support (and donations) to the police force or be abducted, tortured, and killed by the serial murderer.
On one hand, the police force has great income and can do more good works. The harm the murderer is capable of is nothing in comparison to what the police can now do. Have the police acted immorally?
