Judge blocks California from requiring background checks to buy ammunition

(Reuters) - A federal judge has blocked California from enforcing state laws requiring people to undergo background checks when they buy ammunition, calling them unconstitutional.

In a decision made public on Wednesday, U.S. District Judge Roger Benitez in San Diego said the laws "have no historical pedigree," and violate the Second Amendment's right for citizens to keep and bear arms.
