OF COURSE it skews the data. Since cops aren't trained to take a single shot, a large portion of the large-bore shooters are not attempting single-shot stops. This causes the .22 shooters to be vastly overrepresented in the group that IS attempting single-shot stops. Therefore, the percentage of single-shot stops achieved with a .22 is artificially high.
And that's the problem with this whole thread. You're trying to figure out a complex issue with no analysis beyond taking the raw numbers of one data set at face value. You didn't know about the police training issue. How many other factors do we not know about?
You aren't going to convince me. I'll be convinced when I hear it from Massad Ayoob and other experts. But go ahead, carry on with your words of wisdom. I'm out.
