Create a national firearm sales tax whose tax rate is proportional to the national firearm injury/death rate

The taxes collected can go towards the significant medical costs that are attributed to firearm deaths and injuries. Since the tax rate is proportional to the firearm deathy/injury rate it would provide an incentive for the firearm industry and owners of firearms to promote policies to reduce the firearm death and injury rate. The tax can be set in April based on the previous year's firearm death and injury rate. The Centers for Disease control, the Dept. of Justice, or a similar federal entity can tabulate the firearm death and injury statistics. Hospitals and Coroner's offices can receive a recording fee to defray the cost of reporting these statistics to the federal government.
