The Largest Source of Stolen Guns? Parked Cars.

The growing number of firearms kept in vehicles has become a new point of contention in the debates over regulating gun safety.

...There is little question about the scope of the problem. A report issued in May by the gun-control group Everytown for Gun Safety analyzed FBI crime data in 271 American cities, large and small, from 2020 and found that guns stolen from vehicles have become the nation's largest source of stolen firearms ' with an estimated 40,000 guns stolen from cars in those cities alone...

...And as the problem has grown, public health officials and lawmakers, including some in Tennessee, have proposed a rather prosaic solution: encouraging or mandating that gun-toting drivers store their weapons in their vehicles inside of sturdy, lockable gun boxes.

Gun control advocates are hoping that the adoption of the boxes in cars will come to be seen as a solution that both sides of the gun debate can accept, much as both sides encourage the use of gun safes and trigger locks in the home.

I just go one step further and want incentives. You can tie any tax credit to the income, as you want to assist those who would have difficulty affording it. I remember reading 800 pound gun safes are recommended if you can't bolt them down. 200 pound gun safes they can move. I'm not sure what the models are for cars, but manufacturers can be quite inventive. Don't worry about people shooting thousands of rounds, they can afford it and already have safes for their collection. 55% of gun owners own 80% of the guns and there are many large collections. If you accept that guns aren't going away, and that something needs to be done and we have to start somewhere, this is a place to start.
