David Black principal of Tripwire Systems & GRIP (Database tracking)
David has worked in the graffiti and anti social behavior sector for close to 15 years in all aspects of the industry, ranging from mass removals, coatings development, and for the past 10 years, graffiti and anti social behavior auditing and strategy designs for cities ranging in size from 100,000-300,000.

TRIPWIRE rapid apprehension systems, developed by David, have seen hundreds of arrests for graffiti, vandalism, drug trafficking, prostitution and trespass bringing the opportunity for instant, reactive enforcement to all Cities and Law Enforcement allowing an actual means of halting this type of behavior live and during the act.

David’s passion is street by street whole city graffiti auditing , profiling and preparation for a Cities graffiti policy. After performing close to 40 city audits using all manner of databases, auditing tools and methods, David, with the direct consultation with Cities, law enforcement and infrastructure groups moved to design the GRIP tracking server based data system. GRIP has already been hailed as a unique and innovative system as it stands and with our ongoing interaction with various agencies sees it further evolve constantly to ensure it is the ultimate crime fighting tool.

GRIP is being used by whole cities, multiple stakeholders and state rail networks to affordably and expertly manage, track and profile offenders for their law enforcement and provide extended uses for other departments such as sanitation, public works and youth services teams taking in all other crime types.
David has trained and consulted for dozens of cities, gang suppression units, POP teams and CAGE units throughout the United States, Australia, Canada.
