Nine years ago, I lived successful a vicinity successful Atlanta wherever crime was ticking up. People were breaking into cars and pulling firearms retired of mitt boxes. Nobody seemed capable to do thing astir it.A constabulary awesome told maine thing I've ne'er forgotten: much than 70 percent of crime involves a vehicle, and astir of those crimes spell unsolved because constabulary seldom person the licence plate.So I did what engineers do.
