The children who lug guns to school won't be thwarted by new gun laws. Mothers mad at murder might do well to study the success of Mothers Against Drunk Driving. The reason MADD has been effective is because the organization went after the people doing harm, not the instruments of their destruction. They didn't demand to get rid of cars, which, incidentally, kill far more children each year than guns do. A child shot by another child playing with a loaded .357, for instance, would still not be alive today even if laws requiring handgun registration or trigger locks were in place.
Ineffective laws are unnecessary laws, and unnecessary laws are always bad laws.
Surely we have enough of those. The people we might wish to prevent from owning a gun, meanwhile, will never be stopped by more gun laws. I know this instinctively, but also thanks to a gun series I wrote in the early 1980s. That's how long we've been having this chat. I interviewed people who recently had used guns, including a murderer and an almost-rape victim.
