Transferred intent (or transferred malice in English law) is a legal doctrine that holds that, when the intention to harm one individual inadvertently causes a second person to be hurt instead, the perpetrator is still held responsible.
 To be held legally responsible under the law, usually the court must demonstrate that the person has criminal intent, that is, that the person knew another would be harmed by his or her actions and wanted this harm to occur.
 If a murderer intends to kill John, but accidentally kills George instead, the intent is transferred from John to George, and the killer is held to have had criminal intent.
Bonus Army was the popular name for an assemblage of some 43,000 marchers—17,000 U.S. World War I veterans, their families, and affiliated groups—who gathered in Washington, D.C. in the summer of 1932 to demand cash-payment redemption of their service certificates.
 Organizers called the demonstrators the "Bonus Expeditionary Force", to echo the name of World War I's American Expeditionary Forces, while the media referred to them as the "Bonus Army" or "Bonus Marchers".
 The contingent was led by Walter W. Waters, a former sergeant.
The American Personal Responsibility in Food Consumption Act, also known as the Cheeseburger Bill, sought to protect producers and retailers of foods—such as McDonald's Corporation—from an increasing number of suits and class action suits by obese consumers.
 To date these suits have been turned down by the courts, sometimes in strong terms.
 The Act was passed by the U.S. House of Representatives in March 2005,and did receive a Senate vote.
 The Act states that food-producing or retailing corporations cannot be legally held responsible for obesity, heart disease, or other health-related issues caused by consumption of their food, save for situations where actual food quality or handling was held responsible for such issues.
The Protection of Lawful Commerce in Arms Act (PLCAA) is a United States law which protects firearms manufacturers and dealers from being held liable when crimes have been committed with their products.
 However, both manufacturers and dealers can still be held liable for damages resulting from defective products, breach of contract, criminal misconduct, and other actions for which they are directly responsible in much the same manner that any U.S. based manufacturer of consumer products is held responsible.
 They may also be held liable for negligence when they have reason to know a gun is intended for use in a crime.
Alkmund of Derby (or of Lilleshall), also spelt Ealhmund, Alhmund, Alcmund, or Alchmund (d. c. 800) was a son of Alhred of Northumbria.
 After more than twenty years in exile as a result of Northumbrian dynastic struggles, he returned with an army.
 He was killed in about 800, for which King Eardwulf of Northumbria was held responsible.
 Whatever the exact circumstances, his death was regarded as a martyrdom, and Alkmund as a saint.
Culpability, or being culpable, is a measure of the degree to which an agent, such as a person, can be held morally or legally responsible for action and inaction.
 Culpability marks the dividing line between moral evil, like murder, for which someone may be held legally responsible and a randomly occurring event, like earthquakes, for which no human can be held responsible.
 One formulation of the concept is as follows:
George Washington Rappleyea (July 4, 1894 – August 29, 1966), an American metallurgical engineer and the manager of the Cumberland Coal and Iron Company in Dayton, Tennessee.
 He held this position in the summer of 1925 when he became the chief architect of the Scopes Trial.
 During a meeting at Robinson's Drug Store it was Rappleyea who convinced a group of Dayton businessmen to sponsor a test case of the Butler Act, which prohibited the teaching of evolution in the state's schools.
 Rappleyea is held responsible for convincing John T. Scopes to be the defendant in the famous "Monkey" Trial.
 (Note: The name is often spelled "Rappalyea" but the spelling "Rappleyea" is what appears in L. Sprague de Camp's book "The Great Monkey Trial" and the author interviewed Rappleyea before his death.)
The "Berkut" (Ukrainian: Бе́ркут ), eagle in English, specifically the Golden eagle, was the system of special police of the Ukrainian militsiya within the Ministry of Internal Affairs.
 Since late March 2014 its Crimean unit in the self-proclaimed Republic of occupied Crimea defected to the Russian Ministry of Internal Affairs preserving its old name.
 Following the 2014 Ukrainian revolution, when Berkut was held responsible by the new government for most of the Heavenly Hundred civilian deaths, acting Ukrainian Interior Minister Arsen Avakov signed a decree that dissolved the agency.
 As a result of the Russian military intervention in Ukraine (2014–present) and internationally criticized referendum in Crimea the Russian Federation occupied Ukrainian Autonomous Republic of Crimea and Sevastopol and claimed them as federal subjects of Russia on 21 March 2014.
 Three days later Russia announced that the Crimean Berkut unit would preserve its name as part of its defection from the Ukrainian authority to the Russian Interior Ministry.
Moral evil is the result of any morally negative event caused by the intentional action or inaction of an agent, such as a person.
 An example of a moral evil might be murder, or any other evil event for which someone can be held responsible or culpable.
Pelham Davis Glassford (August 8, 1883 – August 9, 1959) was a United States Army officer who attained the rank of brigadier general during World War I.
 He later served as Superintendent of the District of Columbia Police Department, and was in large measure held responsible for the violence that ended the 1932 Bonus Army protests.
