Employee background checks are a key part of recruiting

I have a Question regarding the ethics of standard background checks in the selection of jurors. There Was a case recently in Auburn, NY of a Man Who Appeared for jury duty, the court Informed That He Had a prior conviction in Ohio and Was Then Arrested When a routine background check Revealed That He Had an outstanding warrant for welfare fraud in Ohio . What Are The Legal and Ethical Implications of mandatory background checks on presumably innocent private Fulfilling Citizens Who Are Not Only But Also a civic duty to Legal Requirement? I Know That invasion of privacy isn’t nailed down specifically in the constitution, But Would not this Qualify as unreasonable search? How is this Different from randomly Selecting and Legally Requiring people to Appear at the local police department for criminal screenings? Serious answers only please.
