There are many things that can prevent accidents but there's no reason to derail this thread to reply to your strawman. Suffice it to say I advocate reducing risk wherever you can.
But that wasn't what I said. I said in order to have enough people carrying guns to have one in the right place at the right time with those skills you mention, you would have to have so many additional guns in circulation among young college students that the accidental and rage shooting incidents would most certainly increase the gun fatality rate by well over 32 additional deaths. You can look up the data to see how many fatal accidents there are per gun owned to show that no brainer.
and i said it's not so simple. perhaps you are right, but it's not that simple.
i pointed out that there need only have been one student prevented from concealed carry in any of the involved class rooms to have possibly ended the event more quickly. if we assume 30 students per class, and at least two class rooms involved, we're talking about one in 60 students.
and i think that's a very conservative estimate, and it completely eliminates conjecture of students attempting to save the day that were not completely involved and in necessary risk.
i also pointed out that one can't just attribute accidental gun death rates to the conceal carry demographic. this is a demographic that i would suspect has a habit of being far more safe. do you disagree?
so, no, it's not at all a straw man. i don't understand how you can think it is. if i was unclear in my attempts to make the relavent points i've revisited above, i apologize.
But your version, the one well trained person with the gun, is a fantasy. I can fantasize too.
as i pointed out, there were at least two in my class last term. it's a statistic, not a fantasy. how likely it is, i don't know, but i do know that people that are well trained with firearms do exist.
I fantasize this guy's ex-girlfriend (if that's what set the guy off) recognized the warning signs because we educate everyone about them, and the ex-girlfriend went to police who actually took her seriously and because legislation had been passed that gave police the power to take action before the girl is murdered (rather than just giving her a restraining order and telling her to file a complaint when he violates it so they can arrest him let him out on bail more pissed than before the restraining order, not tell her, and return to kill her). In my fantasy the police arrest this guy before he fires a single shot. They search his residence and find the plan and weapons so he is held without bond, convicted, and by the time he gets out of jail, she's finished college and her can't find her.
I mean as long as you're fantasizing....
to make the above relavent, let's fantasize that the girlfriend needed a permit to approach the police, but that the permit was not valid on school grounds.
in dicussing the merits of any legislation, we need to deal with the hypothetical. it's neither fantacy to suggest that perhaps there were warning signs to which others could have taken notice, nor is it fantacy to suggest that an armed student could have ended this event sooner.
the likelyhood of any of these events may be inferred by statistics. it's not fantacy. it's numbers.
and like i said, i don't know the numbers. i can only make rough guesses.
