Thing is, I can live with the fear of someone in my office or some other place me or my family frequent going bat$hit and shooting the place up. Despite the media attention, we're still way short of the threshold where you're close to the number of people that die each year from random, trivial $hit. A couple hundred people a year or so? Tragic if you're affected just like any car accident or negligent act that leads to death or serious injury, but random.
The Jihadists are different. The only thing stopping them from killing tens or hundreds of thousands of people is access to the technology. I can't see someone who got fired from their job, or even a guy who is crazy and feels isolated like Lanza/Sandy Hook, trying to access and having the means to access and use a nuclear or chemical weapon that could kill tens or hundreds of thousands of people -- enough for centuries more of routine wacko shootings.
On the other hand, any one of these thousands of jihadi a$$holes would do it if they had the opportunity, and they're actively consipiring every day to kill as many as possible, trading tips, building on their collective knowledge, etc. That is their mission.
The gun control debate distracts from that problem in my view. Two different issues.
