Porque sherlock holme es un detective extraordinario? ?

Al referirse a sí mismo como un "detective consultor" en las historias, Holmes es conocido por su habilidad con la observación, la ciencia forense y el razonamiento lógico que raya en lo fantástico, que emplea cuando investiga casos para una amplia variedad de clientes, incluido Scotland Yard .

English:

Referring to himself as a "consulting detective" in the stories, Holmes is known for his proficiency with observation, forensic science, and logical reasoning that borders on the fantastic, which he employs when investigating cases for a wide variety of clients, including Scotland Yard.

the fourth amendment protects:

"the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."  

so this would mean the denial to search and seizure without warrant or permission.
