A lot of people are pointing to a CNN article that references an official statement that the shooter bought the pistol used in the attack himself (and thus passed a NICS check), rather than being given one; despite being under indictment for a disqualifying charge. This is being used as a talking point about the uselessness of BG check. That’s not a good argument against universal background checks, though, certainly not one for our side. It’s an argument for doing away with NICS, yes, but replacing it with the kind of invasive and lengthy background check that predated NICS, and is still in use in NJ and some other places.
We need to be very careful about handing talking points to the other side – pointing out flaws in NICS gives them ammunition to replace it with an actual background investigation.
