I haven’t run down the film clips for these, but we’ve all seen them:
-the character has a pump action shotgun. They rack the pump to show they’re serious. Then they rack again. Ann’s again. Never firing, just racking.
-In a similar vein, they have a semi-auto pistol. To show they’re serious, they cock it and you get the hammer-and -cylinder clicks of a revolver. Never mind that it’s also a glock, or any of the other pistols without an exposed hammer.
-all the crack shot cowboys who make precise quick draw shots at ranges up to 50 yrs or more without ever even glancing at the sights.
The most recent “gun dummy” incident was in a book instead of a movie. A veteran LEO,you after taking another officers glock sidearm, carefully sets the safety before dropping it into his pocket. This author has writes at least three different series of novels, all involving some level of LE, with dozens of books published. I expect better from supposed professional writers.
