June 6 (UPI) -- A fruitless and predictable myopia tends to take over political discussion after gun-spawned tragedies like the massacre in Uvalde, Texas.

Deeply entrenched in their positions, politicians mostly argue over the particulars of the most recent tragedy and how it might have been prevented. A background check? A locked door? In narrow debates, policies are touted or decried based on how applicable they are to the latest killing.

Left aside is a broad range of gun policy proposals that experts in criminology, public health and law enforcement have for years believed are practical solutions to at least part of the nation's enduring problems with gun violence.

And while those experts acknowledge that some of the relatively minor changes might not have prevented the massacre freshest in the public's mind, they can reduce mass shootings. Even more, the policies could greatly reduce gun violence overall, which kills more people in the United States than car crashes.

"The idea that gun laws won't have an impact in reducing mass shootings and school shooting violence is a myth," said Louis Klarevas, a research professor at Teachers College at Columbia University who studies gun violence.
