The severely mentally ill have easy access to guns in Oklahoma, The Oklahoman reported yesterday. Gerald David Hume, a diagnosed schizophrenic, was able to purchase rifles and a handgun at Walmart and Gun World in Oklahoma City in November, which he used to shoot his 77-year-old mother to death. He then dismembered her body.

Prospective gun owners in Oklahoma must fill out seven pages of paperwork, which is sent to the National Instant Criminal Background Check System. Included in that paperwork is a question: “Have you ever been adjudicated mentally defective?” In other words, have you been ruled a danger to yourself or others or committed to a mental institution?

If a person checks “yes,” the sale is canceled. But if the applicant checks “no” and is lying, there is no way to verify that, because Oklahoma law prohibits mental health professionals from sending mental health records to the database. Hume checked “no” on the mental health question before purchasing his guns.

House Bill 1240 sought to close the mental illness loophole by requiring county clerks to submit the names of everyone the court found to be mentally defective, and though it captured a majority vote in the House, it died in a Senate committee in the spring.

“Gun sellers were in favor of getting it done,” Miles Hall, president and founder of H&H Shooting Sports, told the paper. “Why it failed, I have no idea.”

Here is today’s report.
