Possibly. Everyone has the Fourth Amendment right to be protected from unreasonable searches and seizures. If the police found evidence of child abuse through an unlawful search, a Nevada criminal defense attorney would then file a motion to suppress the evidence asking the judge to disregard the illegally-obtained evidence. If the judge grants the motion to suppress, then the district attorney's case against the defendant may be severely weakened. They may even drop the case for lack of proof.
