witnesses

Civil lawsuits alleging wrongful conviction may assert claims including failure of police or prosecutors to disclose exculpatory evidence and coercion of witnesses to give false statements.

Federal judges can revoke a defendant's pretrial release (bond) if the prosecution persuades the court there is a serious risk the defendant will threaten, injure, or intimidate witnesses or jurors.

Law enforcement investigations of shootings commonly include recovering firearms and shell casings, reviewing surveillance video, and interviewing witnesses and potential suspects to establish events and motive.

A district attorney's office can withdraw criminal charges if key victims or witnesses fail to appear in court.

U.S. courts can deny pretrial release (bail) when prosecutors present credible concerns that a defendant may tamper with or intimidate witnesses.

A defense theory in U.S. criminal cases asserts that a witness's answer that is 'literally true' cannot, by itself, support a conviction for making false statements to Congress or federal investigators.

A due-process-based defense argument in criminal law is that questioners must frame their questions with sufficient clarity so that a witness does not have to guess at the intended meaning before answering.

Civil lawsuits challenging wrongful convictions commonly allege failures by law enforcement or prosecutors to disclose exculpatory evidence, coercion of witness statements, and prosecutorial misconduct such as improper or false statements during closing arguments.
