Makes sense. From the article:
"Magazines holding more than 10 rounds were banned for 10 years under the Federal Assault Weapons Ban of 1994. "We cannot clearly credit the ban with any of the nation's recent drop in gun violence," the Department of Justice-funded study concluded in 2004. "Should it be renewed, the ban's effects on gun violence are likely to be small at best and perhaps too small for reliable measurement."
