On Monday the ATF revealed that Jacksonville gunman David Katz had two handguns at the time of his attack and he acquired both of those legally in Baltimore, Maryland.

ABC News reports that Jacksonville Sheriff Michael Williams said Katz was armed with two handguns — a .45 caliber and a 9mm, when he opened fire on fellow gamers at the Madden Tournament. However, Williams added that Katz only used one of the guns in the attack.

The ATF revealed that Katz bought both guns “within the month of August in Baltimore from a licensed dealer.” This means Katz passed a background check to acquire his firearms, and it also means he complied with pre-purchase requirements for would-be handgun purchasers in Maryland.

Katz now joins a growing list of public attackers who have acquired their guns via background checks. That list includes:

Following news of the Jacksonville shooting, but before all the facts were in, gun control proponent David Hogg took to Twitter to urge Congress to require background checks on all gun sales:

Hey @SpeakerRyan – Just a reminder that 97% of Americans support universal background checks for all gun purchases. Why won't you #AllowTheVote? — Andrew Weinstein (@Weinsteinlaw) August 27, 2018

Jacksonville is a yet another reason to oppose expanding background checks, inasmuch as it is demonstrable that such checks pose no hindrance to would-be criminals. They simply create more red tape for law-abiding citizens to wade through in order to acquire guns for self-defense.
