A National Rifle Association-sponsored report on Tuesday proposed a program for schools to train selected staffers as armed security officers. The former Republican congressman who headed the study suggested at least one protector with firearms for every school, saying it would speed responses to attacks. The report’s release served as the gun-rights group’s answer to improving school safety after the gruesome December slayings of 20 first-graders and six adults at a Newtown, Conn., elementary school. And it showed the organization giving little ground in its fight with President Obama over curbing firearms.

Obama’s chief proposals include broader background checks for gun buyers and bans on assault weapons and high-capacity ammunition magazines — both of which the NRA opposes.

The study — unveiled at a news conference watched over by several burly, NRA-provided guards — made eight recommendations, including easing state laws that might bar a trained school staff member from carrying firearms and improving school coordination with law enforcement agencies. But drawing the most attention was its suggested 40- to 60-hour training for school employees who pass background checks to also provide armed protection while at work.

“The presence of an armed security personnel in a school adds a layer of security and diminishes the response time that is beneficial to the overall security,” said Asa Hutchinson, a Republican former congressman from Arkansas who directed the study.

Asked whether every school would be better off with an armed security officer, Hutchinson replied, “Yes,” but acknowledged the decision would be made locally.

Hutchinson said school security could be provided by trained staff members or school resource officers — police officers assigned to schools that some districts already have.

Dan Domenech, executive director of the American Association of School Administrators, said while a trained law enforcement officer with a gun would be valuable, his group opposes arming “a teacher or an employee who simply has taken a course and now has the ability to carry a weapon.”

The Brady Campaign, a leading gun-control group, accused the NRA of “missing the point” by ignoring the need for expanded background checks and other measures the Senate is considering. It said people want “a comprehensive solution that not only addresses tragic school shootings, but also helps prevent the thousands of senseless gun deaths each year.”

Also denouncing the recommendations was Randi Weingarten, president of the American Federation of Teachers, which represents 1.5 million teachers and other workers. She called it a “cruel hoax that will fail to keep our children and schools safe” while helping only gun manufacturers.

The NRA released its report as congressional momentum seems to have stalled for any sweeping steps to curb gun violence.

Top Senate Democrats have little hope for a proposed ban on assault weapons, and the prospects for barring large-capacity magazines also seem difficult. Key senators remain short of a bipartisan compromise on requiring gun transactions between private individuals to undergo federal background checks, which currently apply only to sales handled by licensed gun dealers. The Senate plans to begin debating gun legislation next week.

The 225-page study cost the NRA more than $1 million, Hutchinson said. The task force included several former top officials of federal law enforcement and security agencies.

The proposal won support from Mark Mattioli, whose 6-year-old son James was killed at Newtown.

“These are recommendations for solutions, real solutions that will make our kids safer,” Mattioli said.
