I think this is something that individuals can only judge for themselves based on their own personal circumstances. If you live in the ‘hood where a dozen murders a week happen within 200 yards of your house, then you betcha its worth it. On the other hand my town gets an average of a dozen murders a year, so here, not so much. My local crime scene is more burglary and car theft so the protection I invest in is good locks, a home security system and good security for the car.
