There's so many liberties taken on television shows, but one thing that always annoyed me was the practice of a LEO entering a dark building or dark house, and having to use their flashlight.
Virtually every X-Files episode has that scene where Mulder and Scully enter a house/cave/the woods/abandoned lab/spaceship and to create tension and horror, they swing their flashlights back and forth.
My question to everyone is: Don't you ever just turn on the light switch? For instance, if you are looking in a dark closet, and there is obviously a chain for the light - do you ever just pull it? If you enter a dark office and you think you see a body on the ground and there is a light switch right there, do you ever just turn it on? Do they even have standard operating procedures regarding light switches? It is a televisual trope that cops prefer to explore dark houses with their flashlights rather than flick on the overhead. What is real?
Thanks for your time.
