People tend to hold overly favorable views of their abilities in many social and intellectual domains. The authors suggest that this overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it. Across 4 studies, the authors found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although their test scores put them in the 12th percentile, they estimated themselves to be in the 62nd.
Dude, you think that guys like us are about to get retirement jobs as Army Internment Specialists and run the welcome wagon for FEMA internment camps. You've never been in a self-defense shooting, you've absolutely never investigated one. You laugh at the internet and press when it talks about .9mm Glock revolvers but then embrace them when they tell you stories that you like. In short, you don't know what you don't know and you're not really in a position to give advice on a cop forum about cop investigations.
