As usual, Larry hits the nail on the head in this great post:
Paris. Coming soon to a location near you. Mumbai, Beslan, and a thousand others, we’ve seen this before, and we’ll see it again.
On the personal, local level, this is another example of why you should carry a gun. No, we don’t expect every permit holder to be a Navy SEAL, just a speed bump. The best way to stop a mass shooter is an immediate violent response. At best, you drop them before they can hurt too many people. At worst, congratulations you were a distraction, but even distractions can save lives or derail plans.
Running is great. I’ll never fault somebody who chooses to run or hide when bad things happen. Every one of us has a different level of training, knowledge, and commitment, and what is the right answer for you, isn’t the right answer for your grandma. If you are the kind of person to get involved, you need to have a clue. However, since the only constant of gunfights is that they suck for somebody, you can do everything right and still die. On the bright side you at least bought everybody else some time.
For the pacifistic anti-gun dumb asses on the internet who always crop up in the aftermath of any violent event, bitching about imaginary crossfires, or how fighting back would just make things worse. Just shut up already. You’re children, with a child’s grasp of the subject. When people are being mass butchered, barring tossing hand grenades at the bad guy, it is pretty damned hard to make it worse.
