Interestingly, cops shooting at fleeing suspects is very common in TV shows and movies, but generally considered unacceptable in real life.
I've sometimes wondered if the cops who grew up watching these scenes over and over again as children, might be inadvertently bringing that same behavior into their real life jobs.
Of course the challenge of proving this, is well stated in this quote:
"Does TV viewing really contribute to all those reactions? ...At the heart of the debate is the difficulty of proving that one thing causes another...Similarly, it has been difficult to prove that the violence shown on television causes crime and antisocial behavior...A Canadian psychologist wrote: “The scientific evidence simply does not show that watching violence either produces violence in people or desensitizes them to it.” However, the American Psychological Association Committee on Media and Society said: “There is absolutely no doubt that higher levels of viewing violence on television are correlated with increased acceptance of aggressive attitudes and increased aggressive behavior.”"

However, among past social circles of mine, I can definitely say TV helped normalize behaviors that at one time weren't as common.
For example, I saw gangster rap, and all of the forms of entertainment that accompanied it's rise in the 90's, dramatically normalize arrogant and aggressive behavior among my peers in suburbia.
So to me, it's logical that TV and movies are one part of the cultural fabric that can indoctrinate new behaviors in the real world. Some of them really unfortunate.
