One thing that really needs to be discussed is the concept of "first do no harm"; that if during an attempt to stop an active shooter you injure others you are simply adding to the damage.
Sure. That makes perfect sense. Shooting without a target, or without some kind of discipline is not like to make the situation better and could make it a lot worse. Again, I'm not telling people what to do or saying what permit holders need to do in the situations, just pointing out how the facts of this situation have changed the claims I will make about permit holders and mass shootings in the future.
There's a BIG difference between a permit holder and someone actually carrying a firearm. Being that at most only 10-15% of permit holders carry all the time that brings the number down to 2-3 people carrying firearms in the store.
I agree with what you're saying 100%. In fact, that's my point exactly. It's not honest for us to claim that permit holders are likely to make a difference in mass shootings when so few of them carry. That's why I won't be making that claim any longer.
They COULD make a difference--it's just not likely given how few permit holders actually carry and the fact that based on what permit holders state here--many of those who do are reticent (and for good reason) to intervene if they can escape instead.
~1000 Mexican nationals
~1000 recent immigrants or illegals
If you look at the first numbers I ran, they used exactly the estimate that 2000 of the 3000 present were unlikely to be TX citizens but used the permit holder figures for the entire state rather than specifically for El Paso County. So I think that's a reasonable number.
~ 500 children, it was a Saturday after all
I used population figures for my calculations--those numbers include children. It is true that children can't get permits, but if one considers that out of the ENTIRE population of El Paso County (including children) 1 out of 44 persons are permit holders then you don't have to exclude children from your estimate because that factor is already incorporated into the estimate.
That brings us down to around 500 people who MIGHT have a permit. Since there are ~1-44 that hold permits in that county that brings us down to 11 people who MIGHT have a permit.
Because the estimate is based on the distribution of permit holders across the entire population of El Paso County (including children) the entire remaining 1000 persons would be used in conjunction with the 1:44 number. If one wishes to exclude children, they should be excluded BOTH from the population figures (which would raise the likelihood of permits in the remaining population) and also excluded from the number of TX citizens in the store (which would decrease the number of persons on the population in question). But assuming the distribution of children in the "population" of the store is similar to the distribution of children in the population of the county, it would be a wash.
Using 1000 as the estimated number of TX citizens in the store (yes, including children) and 1:44 as the permit holder distribution amongst the population of El Paso County (also including children) indicates that it is very likely (better than 99% confidence level) that there were 23 (plus or minus 2) permit holders in the store.
As you point out, however, most permit holders do not carry and of the ones that do, some (perhaps many) have decided in advance not to intervene unless they have no other choice.
All of that is why I can no longer, in good conscience, continue to assert that permit holders are likely to be a factor in mass shootings.
