Second, every gun should be licensed and registered, and the approvals process should be stringent. Although there are logistical difficulties to obtaining information about guns already in the market, it's relatively straightforward to mandate for any new guns sold.
My final point is critical. Pro-gun advocates argue constantly about rights, which is fine. Yet with any right comes responsibility. Given the potential consequences, the right to bear arms should be tightly wedded to meaningful responsibility. So here's the proposal: All guns must be registered to one individual, and that individual is responsible for that gun and for any crimes committed with that weapon. If the gun is lost or stolen, it must be promptly reported to the police, at which point the burden of responsibility shifts.
Otherwise, crimes committed using your gun are your crimes.
This isn't a nuanced proposal from a gun control expert. It's a common sense outline from a father who doesn't want to worry about sending his child to school.
