Racial profiling is the act of suspecting, targeting or discriminating against a person on the basis of their ethnicity or religion, rather than on individual suspicion. Racial profiling often involves discrimination against minority populations and builds on any negative stereotypes of the targeted demographic. Racial profiling, however, is not limited only to an individual's ethnicity, race or religion and can also be based on the individual's nationality. In European countries, the term ethnic profiling is also used instead of "racial profiling".
Burden of proof is a legal duty that encompasses two connected but separate ideas that apply for establishing the truth of facts in a trial before tribunals in the United States: the "burden of production" and the "burden of persuasion." In a legal dispute, one party is initially presumed to be correct, while the other side bears the burden of producing evidence persuasive enough to establish the truth of facts needed to satisfy all the required legal elements of legal dispute. There are varying types of burden of persuasion commonly referred to as standards of proof, and depending on the type of case, the standard of proof will be higher or lower. Burdens of persuasion and production may be of different standards for each party, in different phases of litigation. The burden of production is a minimal burden to produce at least enough evidence for the trier of fact to consider a disputed claim. After litigants have met the burden of production, they have the burden of persuasion: that enough evidence has been presented to persuade the trier of fact that their side is correct. There are different standards of persuasiveness ranging from a preponderance of the evidence, where there is just enough evidence to tip the balance, to proof beyond a reasonable doubt, as in United States criminal courts.
In United States criminal law, probable cause is the standard by which police authorities have reason to obtain a warrant for the arrest of a suspected criminal or the issuing of a search warrant. It is also the standard by which grand juries issue criminal indictments. The principle behind the standard is to limit the power of authorities to perform random or abusive searches, and to promote lawful evidence gathering and procedural form during criminal arrest and prosecution. The standard also applies to personal or property searches.
Entrapment is a practice in which a law enforcement agent or agent of the state induces a person to commit a "crime" that the person would have otherwise been unlikely or unwilling to commit. It "is the conception and planning of an offense by an officer or agent, and the procurement of its commission by one who would not have perpetrated it except for the trickery, persuasion or fraud of the officer or state agent".
The presumption of innocence is a legal principle that every person accused of any crime is considered innocent until proven guilty. Under the presumption of innocence, the legal burden of proof is thus on the prosecution, which must present compelling evidence to the trier of fact. If the prosecution does not prove the charges true, then the person is acquitted of the charges. The prosecution must in most cases prove that the accused is guilty beyond a reasonable doubt. If reasonable doubt remains, the accused must be acquitted. The opposite system is a presumption of guilt.
A Terry stop in the United States allows the police to briefly detain a person based on reasonable suspicion of involvement in criminal activity. Reasonable suspicion is a lower standard than probable cause which is needed for arrest. When police stop and search a pedestrian, this is commonly known as a stop and frisk. When police stop an automobile, this is known as a traffic stop. If the police stop a motor vehicle on minor infringements in order to investigate other suspected criminal activity, this is known as a pretextual stop. Additional rules apply to stops that occur on a bus.
False arrest is a common law tort, where a plaintiff alleges they were held in custody without probable cause, or without an order issued by a court of competent jurisdiction. Although it is possible to sue law enforcement officials for false arrest, the usual defendants in such cases are private security firms.
California v. Greenwood, 486 U.S. 35 (1988), was a case in which the Supreme Court of the United States held that the Fourth Amendment does not prohibit the warrantless search and seizure of garbage left for collection outside the curtilage of a home.
Atwater v. Lago Vista, 532 U.S. 318 (2001), was a United States Supreme Court decision which held that a person's Fourth Amendment rights are not violated when the subject is arrested for driving without a seatbelt. The court ruled that such an arrest for a misdemeanor that is punishable only by a fine does not constitute an unreasonable seizure under the Fourth Amendment.
Knock-and-announce, in United States law criminal procedure, is an ancient common law principle, incorporated into the Fourth Amendment, which requires law enforcement officers to announce their presence and provide residents with an opportunity to open the door prior to a search.
Self-defence is a defence permitting reasonable force to be used to defend one's self or another. This defence arises both from common law and the Criminal Law Act 1967. Self-defence is a justification defence rather than an excuse.
Illinois v. Wardlow, 528 U.S. 119 (2000), is a case decided before the United States Supreme Court involving U.S. criminal procedure regarding searches and seizures.
Whren v. United States, 517 U.S. 806 (1996), was a unanimous United States Supreme Court decision that "declared that any traffic offense committed by a driver was a legitimate legal basis for a stop."
South African criminal law is the body of national law relating to crime in South Africa. In the definition of Van der Walt et al., a crime is "conduct which common or statute law prohibits and expressly or impliedly subjects to punishment remissible by the state alone and which the offender cannot avoid by his own act once he has been convicted." Crime involves the infliction of harm against society. The function or object of criminal law is to provide a social mechanism with which to coerce members of society to abstain from conduct that is harmful to the interests of society.
Criminal procedure in South Africa refers to the adjudication process of that country's criminal law. It forms part of procedural or adjectival law, and describes the means by which its substantive counterpart, South African criminal law, is applied. It has its basis mainly in English law.

Floyd, et al. v. City of New York, et al., 959 F. Supp. 2d 540, is a set of cases addressing the class action lawsuit filed against the City of New York, Police Commissioner Raymond Kelly, Mayor Michael Bloomberg, and named and unnamed New York City police officers ("Defendants"), alleging that defendants have implemented and sanctioned a policy, practice, and/or custom of unconstitutional stops and frisks by the New York Police Department ("NYPD") on the basis of race and/or national origin, in violation of Section 1983 of title forty-two of the United States Code, the Fourth and Fourteenth Amendments to the United States Constitution, Title VI of the Civil Rights Act of 1964, and the Constitution and laws of the State of New York.
In S v Fernandez, an important case in South African criminal law, heard on February 17, 1966, the court held that the appellant had been negligent in mending a cage from which a baboon had subsequently escaped, which subsequently bit a child, who subsequently died. The appellant must have foreseen the likelihood of an attack in the event of the baboon's escaping; he was, the court held, therefore rightly convicted of culpable homicide. The case was an appeal from a decision in the Transvaal Provincial Division by Galgut J and Clayden J, who had dismissed an appeal from a conviction in a magistrate's court.
