But how significant is the police market? Do manufactures have a significant incentive to participate in this attempt?
NICS checks (a proxy for private citizen gun sales):
Approximate number of state and local police officers with arrest authority: (2008 appears to be the most recently available data) 800,000.
Using the given facts and assumptions the participating agencies would account for annual sales of about 200,000 firearms.
The net new firearms supply in the U.S. is about 11,000,000 (U.S. manufactured plus imported minus exports).
Private citizen sales, including used guns, is something on the order of 16,000,000 to 19,000,000 per year. Therefore civilian sales are a major portion of the total new firearms sales.
The “back of the envelope” estimate is that even using the optimistic assumption that a fourth of sales to law enforcement officers would contribute to the infringement that would only account for less than 2% of all new gun sales.
Any manufacture which considers going along with this will also give extremely serious consideration to the effect on Smith and Wesson when they collaborated with the enemy.
Jersey City attempts to push manufactures into assisting them in their attempts to infringe upon the rights of the people to keep and bear arms will be ignored, if not actively rejected, by firearm and ammunition suppliers.
Whoever thought up this screwball plan did not do, or is incapable of, simple arithmetic involving easily available data. But one should not be surprised. We know these people have mental problems.
