Most uses of a firearm in cities are by people who are already prohibited from having/buying one.
They will use stolen or straw purchased guns that are passed from prohibited person to prohibited person for as little as $50 until someone is caught with it.
Now the tech behind this actually helps the police find unreported gunshots and run reports on where most gunshots occur so they can focus their attention on that area. I don't find that troublesome in the least. As a country with high firearm ownership there are always going to be certain problems, so we try to mitigate those issues with tech.
these people are murderers. they buy illegal guns illegally, to commit illegal crimes. they don't care about your laws. you could make all guns illegal tomorrow and they would still have guns.
The solution to the gunshots problem is before the guns shoot, like background checks required to own a weapon.
That a company could make an IPO over such an idea goes very, very far in describing today's America.
Soon to come: the laptop you can assembly yourself and that can be carried in the cabin?
