From the Daily Democrat:

The gun dealers’ holiday season got off to a rousing start. State data show that sales transactions spiked on Black Friday — the traditional start of the holiday shopping season — to four times the average number for other November days.

That spike was roughly double the uptick in the days after Syed Farook and Tashfeen Malik, armed with two semi-automatic rifles and two semi-automatic handguns, killed 14 and injured 21 in a hail of bullets Dec. 2 at the Inland Regional Center in San Bernardino. All of their firearms were purchased legally in California, which has some of the nation’s strictest gun laws.
