Now, the reason why a search warrant is important is because it interposes a judge in the relationship between investigators and the citizens, and that judge's job is to make sure that there's good cause for the surveillance, that the surveillance is targeted at the right people, and that the information that's collected is going to be used for legitimate government purposes and not for discriminatory ones.
Una orden de registro es importante porque pone de por medio a un juez en la relación entre los investigadores y los ciudadanos. Y la tarea del juez es asegurar que existan causas justas para la vigilancia y que esta sea dirigida a las personas correctas, y que la información obtenida se use para fines legítimos del gobierno y no para fines discriminatorios.
