New York Times Pressures Credit Card Giants to Blacklist Gun Purchasers

Two days before Omar Mateen killed 49 people and wounded 53 more at the Pulse nightclub in Orlando, he went on Google and typed “Credit card unusual spending.” Mr. Mateen had opened six new credit card accounts — including a Mastercard, an American Express card and three Visa cards — over the previous eight months. Twelve days before the shooting, he began a $26,532 buying spree: a Sig Sauer MCX .223-caliber rifle, a Glock 17 9-millimeter semiautomatic pistol, several large magazines, thousands of rounds of ammunition and a $7,500 ring for his wife that he bought on a jewelry store card. His average spending before that, on his only card, was $1,500 a month.

A little more than a month before James E. Holmes killed 12 people and injured 70 others at a Century 16 movie theater in Aurora, Colo., in 2012, a psychiatrist was considering having him involuntarily committed. Mr. Holmes quit his job, filed for unemployment benefits and used a new Mastercard issued by USAA to help buy more than $11,000 in weapons and military gear. He bought two tear-gas grenades, a gas mask and filter, a .40-caliber Glock handgun, a 12-gauge shotgun, a .223-caliber AR-15, a 100-round drum magazine, two 40-round magazines, a laser sight, a bulletproof vest, 5,000 rounds of ammunition, two sets of handcuffs and “road stars” meant to slice through car tires.
