Neighborhood watch

I have been talking to a few of my neighbors recently about forming some type of a neighborhood watch as sort of a round about way of getting them prepared for the possibility of us being left to defend ourselves here within the near future. For the most part I seem to be spinning my wheels, nobody has shown any real interest in doing anything that takes them out of their routine or their comfort zone. If anyone reading this has any ideas on how to approach them without sounding all doom and gloom, I'd love to hear your ideas.
