I'm so glad we went through that whole 'Detective Bell getting shot in no small part to Holmes disregarding police procedure' drama, because of it -Holmes had to face the unintended consequences of his reckless methodologies and grew an appreciation for the precautions that the NYPD takes.
Without that whole affair -Holmes might have continued to flout all procedure while expecting no negative and unintended consequences. He might say; have sex with the NYPD's prime suspect in a homicide. . .
