Now that you've become the laughing-stock of gun salespersons to those groups, what did you learn? You need to vastly boost the reliability of such devices before even thinking of trying to sell them to serious buyers. Once the device failure rate improves by a few orders of magnitude, then try again. The actual number the military is looking for is of far higher reliability than a 0.5% error rate.
you are a 0.00001% of the population who does
0.00001% * 320 million people = 32 people. Methinks there are a few orders of magnitude more than your proposed count.
If a piece of software flags & sends notices about 300 items a minute and even 10% of them are false, that's 4320 false claims a day. If it is a $500 fine per false claim that's on the order of 2 million dollars lost a day. Hmmm...this is sounding better and better all the time...
