Your whole argument seems to be premised on the number of rounds a magazine can hold. To me there really is no dramatic difference between a 20 round mag, a 10 round mag, or a 5 round mag. Anyone who knows how to use an "assault" weapon or any gun for that matter can probably change a magazine in 2 seconds. An insignificant amount of time really given the intention of the possibly situation.. Plus with tactical gear vests it makes it easier than ever... The problem with your argument is you want to save some lives by trying to find solutions for potential gun related situations with non-scientific theory and/or self opinion. For me, I want to find solutions so these types of events never even start.
I want to find solutions so that these issues should not need to be discussed in government and on message boards. Read some of my other posts.
My argument isn't scientific because it can't ever be scientific. How can we test the effects of reduced magazine size on the number of lives lost without actually having some raw data? How can we get that raw data? The only way we can do that is to run the same person through the same course in the same amount of time and measure how many people (critically hit dummies) the person hit. Then run an ANOVA to see if that difference was significant. That's how the argument becomes scientific.
The problem with that test is the fact that there are an incredible amount of confounds that really invalidate the findings. Not everybody operates a gun with the same amount of efficiency or accuracy (and even then a single person's efficiency changes on a daily (even hourly, basis), not every building is going to be laid out like the course, the reaction time of the targets (real people) are not the same. All of those can critically affect the effect of reduced magazines on the number of lives lost. So my argument can never be scientific.
But why can't it be researched? Answer that question and you'll find the real culprit. It has just three letters. N. R. A.
You're essentially saying "..'This' many people shouldn't die in this type of event, because if we did this only 'this' many people would die." You don't even realize it, but by your logic you're admitting that we wouldn't even solve the actual real problem.
