A criminal defense lawyer is a lawyer (mostly barristers) specializing in the defense of individuals and companies charged with criminal activity. Some criminal defense lawyers are privately retained, while others are employed by the various jurisdictions with criminal courts for appointment to represent indigent persons; the latter are generally called public defenders. The terminology is imprecise because each jurisdiction may have different practices with various levels of input from state and federal law or consent decrees. Some jurisdictions use a rotating system of appointments with judges appointing a private practice attorney or firm for each case. Source: https://en.wikipedia.org/wiki/Criminal_defense_lawyer
