Pale Background - how few crime guns will be caught with "universal" background checks

"Since it has been known for decades that a minimum of 40% of crime guns come from street sources, the entire push for “universal” background checks is an exercise in stupidity. It does not address the common, recurring, and majority source of crime guns. The effort is better diverted to fixing the street problem."
