Let the kids run in circles, screaming. Proper control? Really? Teachers unable to defend themselves and their children HAVE NO CONTROL, THEMSELVES. They are at the mercy of the shooter. How safe were the orderly children in Newtown?

Vicki Soto had enough time to shepherd her kids into cabinets and wait for the shooter to come in and kill her. That would have been plenty of time to draw and fire. Honey.

I hear what you're saying on the first part. I do wonder about the unintended consequences of having CCW in school would be, as it relates to escalating violent situations already present in schools. It doesn't seem to be a problem for the SROs (no kids seem to be bum rushing them to take their guns). But, this…

My heart is just breaking for their systematic disenfranchisement that leads them to hurt innocent people. Again, clearly beyond the scope of this discussion, but thanks for the psychoanalysis. And for the insults. Nothing says "solid argument" like an ad hominem attack.

Do schools not have lockable doors? (I ask this seriously.) Of course, that only helps classrooms 2 through X. Classroom 1 getting shot up will be the alarm for the other classrooms to lock it down.

What are your friends' names, and what SEAL group(s) were they with? Because, if they told you that, they were talking out their asses.

SROs are great, if you can get them and pay for them. They are expensive, though.

My aim is OK; it's nothing to write home about. I know I could use a handgun to shoot a person from the width of a classroom away. So could just about any person with even the most rudimentary firearms training and practice.

You might be surprised to learn how little firearms training and testing many police officers do, and especially how unprepared most police officers would be in an active shooter scenario, since one needs to practice sound tactics to act offensively against a shooting, suicidal threat. Although, the ones posted in…

On first aid: can you cite your source on CPR and/or AEDs hurting more often than helping? Seems like a lot of Red Cross classes and AED machines exist, for them to be more likely to hurt.

Gosh, I never even thought of aiming. Thank goodness you jumped into the discussion. Kickback? You clearly know your weapons terminology, ya know.

Then don't carry one. No one is suggesting teacher CCW should be mandatory, just that it not be prohibited for those who wish to do it. Those so inclined would likely be proficient and willing to engage, and their possible presence in every classroom makes attacking any classroom a much less attractive endeavor. …

These are good points. It would certainly be worth a look at the potential negatives of CCW vis-a-vis violent, unpredictable students who are prone to heat-of-the-moment situations, although my initial reaction would be to expel students or disband schools where students exhibit that sort of thuggish, prison yard…

You certainly have a lot to say about shooting and defensive tactics. What are your qualifications in those areas, if you please? I'm a former military combat aircrew officer, a certified firearms instructor, a CHL holder in three states, and a person with 36 years of shooting experience with rifles, shotguns, and…

You wear it on your person, or you lock it in your drawer and keep the keys on your person. If you hear shooting, you get the gun, you tell the kids to go to the corner, and you stand in a different corner, pointing your gun at the door. If the door opens and the person coming through it has his own gun out and is…

Just because one owns a gun and knows how to use it for self protection does not mean a) one wants to do so, and b) one's success will be guaranteed. Like vaccinations and fire extinguishers, guns greatly improve the odds; they are not foolproof.

We can't keep weapons from entering and killing from happening in prisons. What makes you think you can stop either in a country of 4M square miles. The arrogance...

I've flown with mine in my wallet four round-trips in the last two years. Either the TSA doesn't see it, or they don't care.

What does this anti-gun tirade have to do with technology? The AR-15 was designed in the 1950s and has been sold to civilians in the exact same form since the early 60s. I don't come to Gizmodo to hear this sort of political editorializing.

I agree. Our views differ. My summary:
