Bandied about seemingly everywhere but in Kentucky.
While gun violence in the U.S. has significantly declined since the 1990s, mass public shootings are on the rise, and schools are now viewed as vulnerable targets. One of the deadliest in history claimed 28 lives, including 20 children, after Adam Lanza opened fire at Sandy Hook Elementary School in Newtown, Conn., in 2012.
Last October, a gunman fatally shot nine people at Umpqua Community College in Roseburg, Ore.
These incidents, and every school shooting in between, have sent mourning parents and distraught education officials on a search for effective preventative measures.
One that has long been bandied about, and now being tested in schools countrywide, is allowing teachers to bring guns to school.
