Police using aerosol can's distinct audio signature to bust graffiti artists. An Escondido, CA company, Traptech, offers an area monitoring system, Taggertrap, to law enforcement that allegedly distinguishes the sound of an aerosol can in the act of spraying. How soon before someone builds an aerosol audio signature cancellation device to fight back?
