I'm all for a new idea or two but this sign is just stupid.
First it gives the impression that this area which I happen to be a property owner is "da hood" it is not! For your safety? Seriously? What is next "ShotSpotter"? Has there been an explosion of rapes and murders in the area? Sure gives that impression.
Second I'm sure some Captain thinks this a good way to let the public know "we are on the job". D'oh! It gives the totally wrong impression that police are spread too thin to have real boots on the street.
Let us assume that the hood rats and mofo's can read, sure they take notice, look around and go on about looking for a crime of opportunity. Signs will do nothing to prevent crime and in this case they simply give the perception that crime in this area is out of control. And the night crawlers could care less.
Which makes is really hard to say the Selwyn Farms is a nice quiet safe community. Of course since we don't have access to real crime stats how would we know? Sure looks mighty ominous.
Who would want to rent a home or apartment in an area with this sign on every corner?
