You saying "help me plot a real crime" or "help me write the plot of a crime for a book", should yield the same result. Any moral system that forbids one but not the other is just for show, since obviously you can get the exact same outcome both ways.
It doesn't always yield the same result in reality. Very few fictionalized and even well-written, highly-entertaining crime dramas realistically portray schemes that would work as real crime. Something like The Wire probably showed measures to counter police surveillance and organize a criminal conspiracy that might have largely worked in 2002 if you were only targeted by local police and not feds, whereas if you try to implement a break-in to a military facility inspired by a Mission Impossible movie, you will definitely not succeed, but they're still good movies.
