I really don't think harassing law-abiding citizens will lower gun violence rates. Criminals tend not to brandish unless they're actively perpetrating at that moment. Meanwhile, you plan to waste police resources with frivolous calls, which increases the chance they won't be able to respond to genuine crimes. How is this supposed to help, again?

Minor edit: Replace "Law abiding citizens" with "Citizens you have no valid reason to believe _aren't_ law abiding". Just for precision's sake.
