From the piece:
But the Assault Weapons Ban is and always has been a bit of a red herring, so people concerned about gun violence shouldn’t be too sad to see it go. Of all the policy proposals to prevent gun violence, it’s probably the least important and the most controversial, making it the ideal sacrificial sacred cow to appease gun rights advocates and to help secure passage of more effective strategies to curbing gun deaths, like a ban on large capacity ammunition magazines.
Shedding the ban makes it possible to do effective gun control without even touching guns.
Why aren’t assault weapons that important? Mostly because they’re used so rarely — as few as 2 percent of all gun crimes, according to the official study mandated by Congress when it passed the 1994 version of the ban. So any legislation on assault weapons can only ever hope to impact a tiny fraction of all gun deaths.
This is a rare case where the NRA is right.
