A national law enforcement group called for gun-control measures, including expanding background checks for firearm purchasers and banning high-capacity ammunition magazines.
The National Law Enforcement Partnership to Prevent Gun Violence, an alliance of nine police leadership organizations, made its announcement at a Thursday press conference at the National Press Club in Washington, D.C.
The group called on lawmakers to pass "effective, common-sense public safety measures strengthening gun laws, while not diminishing law-abiding gun owners' ability to own and use firearms," according to a statement from the group.
James Johnson, the Baltimore County, Md., police chief, said a high-capacity magazine like one used in the Aurora shooting "simply has no place in civilian hands," reports the Los Angeles Times.
"It is ridiculous to argue that hunters or civilians who own weapons for self-defense need a 100-round drum magazine," he said. "As we have seen, people don't stand a chance against this kind of firepower."
