We need a detection system, available for use and in use by most Americans, to track and profile the purchases of weapons to kill in the US. Currently we track items such as Sudafed (meth), moonshine, higher than average alcohol content beer, various Groupons and Price Checks on the intenet. Why can't we use the same commerce-based profiling techniques provided by Credit Bureaus and Marketing databases to give us intelligence on the availability, use, population, risk, and types of weapons being sold in the US.
Attach a Health Information Exchange's data element for Mental Health Assessment/Background check to a person's commercial credit score to systematically provide a cross-check to gun purchases.
