In the past, Scotland Yard police officers believed that Sherlock was a freak who would sooner or later commit a crime.
Now they understand that Shylock is a man with a great sense of justice and deserves their respect.
Previous media:
"Sherlock Holmes is a high-functioning sociopath and a drug addict. Even if he helps the police solve the case, he is still a hidden danger to society."
Now:
"Sherlock is a hero and we should pay tribute to him!"
Sherlock: "No, you misunderstood, I didn't want to..."
It's hard for me to be forced by the system to solve the case!
Purpose: I saw the Scotland Yard police officers calling Sherlock a "freak" and wanted to change that and tell them that Sherlock was a good man.
