Its my understanding the gunman used a 100 round drum magazine. If so the NRA is rightly going to get hammered over this.
This is why I gave up my NRA membership long ago, their extremism and complete and total inflexibility is actually doing more harm than good in the long run. They give reponsible gun owners a bad name.
So it's the magazines fault this guy committed mulitple murders? Would it have been better if he had four 30 round mags, and took a second to reload?
Reports are that the 100 rd drum mag caused the AR to jam, so he had to use his Glocks, and shotgun.
I don't understand why the tool in any configuration is being blamed.
