US SUPREME COURT DECISIONS REGARDING HANDWRITING AS FORENSIC EVIDENCE OR TOOLS FOR EMPLOYEE SCREENING
In 1973 the Supreme Court held that the Fourth Amendment is not violated by a compelled production of ‘physical characteristics’ that are constantly exposed to the public. The court stated: “Handwriting, like speech, is repeatedly shown to the public and there is no more expectation of privacy in the physical characteristics of a person’s script than there is in the tone of his voice.”
