Is the warrantless search of a First Class sealed mail Priority package by a United States Postal Service mail carrier during the course and scope of her employment "government action" by a "government actor" which violates the Fourth Amendment's prohibition against unreasonable searches and seizures, thus requiring the evidence seized to be suppressed?

Did the Fifth Circuit correctly hold that a mail carrier was not a government actor for the purposes of the Fourth Amendment because her warrantless search of the Priority package was made for personal reasons or out of a personal motivation, "because of her concern for children and her experience with a relative". . . and [she was] not inspecting the package to enforce the law, or a government actor who undertook law-enforcement activities?
