The Paramythia executions, also known as the Paramythia massacre (19–29 September 1943) was a combined Nazi and Cham Albanian war crime perpetrated by members of the 1st Mountain Division and the Muslim Cham militia in the town of Paramythia and its surrounding region, during the Axis occupation of Greece.
 201 Greek villagers were murdered and 19 municipalities in the region of Paramythia were destroyed.
 The years after the war, a series a war crime trials condemned these actions, however not a single defendant was ever arrested and brought to trial.
 At the Hostages Trial in Nuremberg (1948) the American judges reached the decision that the executions of Paramythia were "plain murders".
Brian Gene Nichols (born December 10, 1971) is known for his escape and killing spree in the Fulton County Courthouse in Atlanta, Georgia, on March 11, 2005.
 Nichols was on trial for rape when he escaped from custody and murdered the judge presiding over his trial, a court reporter, a sheriff's deputy and later a federal agent.
 Twenty-six hours after a large-scale manhunt was launched in the metropolitan Atlanta area, Nichols was taken into custody.
 The prosecution charged him with committing 54 crimes during the escape; and he was found guilty on all counts on November 7, 2008.
Bail is money or some form of property that is deposited or pledged to a court, in order to secure the release from custody or jail of a suspect who has been arrested, with the understanding that the suspect will return for their trial and required court appearances.
 Bail is a mechanism to release suspects from imprisonment pre-trial, while ensuring their return for trial.
 If the suspect does not return to court, the bail is forfeited, and the suspect may possibly be brought up on charges of the crime of failure to appear.
 If the suspect returns to make all their required appearances, bail is returned after the trial is concluded.
 In some cases, bail money may be returned at the end of the trial, if all court appearances are made, regardless of whether the person is found guilty or not guilty of the crime accused.

A legal drama or a courtroom drama is a subgenre of drama and crime fiction.
 Law enforcement, crime, detective-based mystery solving, lawyer work, civil litigation, etc., are all possible focuses of legal dramas.
 Common subgenres of legal dramas include detective dramas, police dramas, courtroom dramas, legal thrillers, etc.
 Legal dramas appear in many forms of media, including novels, plays, television shows, and films. Legal drama sometimes overlap with crime drama, most notably in the case of "Law & Order".
 Most crime drama focus on crime investigation and does not feature the court room.
 An early example of this overlapping form was Erle Stanley Gardner's Perry Mason, in which the eponymous trial lawyer would usually defend his clients from their murder charges by investigating the crime before the trial, and dramatically revealing the actual perpetrator during the closing courtroom scene, by calling some other person to the stand and interrogating him or her into confessing in open court:
Edna Phillips was a 70-year-old woman who was murdered on 16 July 1992 by two teenage girls, one of them her next-door neighbour, at her home on a council estate in Penywaun in South Wales.
 The details of the crime were made public soon after the start of the trial of the two boys who murdered two-year-old James Bulger in Merseyside, which contributed to the resulting moral panic in the United Kingdom.
