The author of this book has some observations on police shootings. Essentially, they are engaging in “display behavior.” Think of a cat fluffing up to look bigger and hissing. Nobody should carry a gun before reading this book. (Also, had a relative involved with the study of a military police shooting where the cops fired 200 rounds and hit none of the suspects despite the danger presented to the exposed under cover agent. The take on it was, they were so afraid of what killing somebody would do to their careers they were incapable of shooting to kill, or even hit, the perps. The report was changed by a general as the conclusions were unacceptable.)
