Artistic License....
In the rareified air that is Hollywood, producers & prodcos(production companies) call it; "artistic license".
There are a few posts & topics here and on other forums about Hollywood goofs/flubs.
Just remember that most screenwriters, actors, producers, etc are NOT cops, soldiers, NRA board members, etc. John Milius(Dirty Harry) being a rare exception. Lol.
I've posted a few "gems" before but one of the most common gun flaws I see is the loading or chambering of a round. I watched a low budget, "hard R" action film on cable where the main hero carefully approached a building to look for danger. The police detective drew his Glock pistol and loaded a round. Then for some unknown reason, he did it 2 more times as he cleared the bldg! Huh???
I'd like to see a cop show or movie where a live round pops up in the air when they do it.

PS; honorable mention goes to shows where somehow good guys or gals can pack N frame revolvers, 12ga shotguns or Desert Eagle pistols concealed with no effort. Even Mad Magazine made fun of that goof-up.
