Mr. Green Jeans asks..."Why do you think they have so many walled and guarded neighborhoods"?

In part Mr Green Jeans because even the most "responsible" gun owners among them can't resist posting on the Internet a description of their firearms inventory and then on Facebook or other sites where they frequently announce to the world that they are on day's outing, on vacation or going out for dinner!

From all initial reports, the Las Vegas shooter acquired all his firearms "legally".  Can you imagine how the former owner of a "legal" firearm stolen in a robbery might feel if the police showed up with his or her gun after it was no longer needed as evidence in a mass shooting?

That's probably a life changing scenario most 2nd Amendment advocates haven't considered and while the odds are probably against it...what were the odds in Las Vegas, Roseburg Oregon, Charleston...
