A detective is an investigator, usually a member of a law enforcement agency. They often collect information to solve crimes by talking to witnesses and informants, collecting physical evidence, or searching records in databases. This leads them to arrest criminals and enable them to be convicted in court. A detective may work for the police or privately.
An arrest warrant is a warrant issued by a judge or magistrate on behalf of the state which authorizes the arrest and detention of an individual or the search and seizure of an individual's property.
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. There is no universally accepted definition or formulation for probable cause. One traditional definition, which comes from the U.S. Supreme Court's 1964 decision Beck v. Ohio, is when "whether at [the moment of arrest] the facts and circumstances within [an officer's] knowledge and of which they had reasonably trustworthy information [are] sufficient to warrant a prudent [person] in believing that [a suspect] had committed or was committing an offense."
An arrest is the act of apprehending and taking a person into custody, usually because the person has been suspected of or observed committing a crime. After being taken into custody, the person can be questioned further and/or charged. An arrest is a procedure in a criminal justice system, sometimes it is also done after a court warrant for the arrest.
The right to silence is a legal principle which guarantees any individual the right to refuse to answer questions from law enforcement officers or court officials. It is a legal right recognized, explicitly or by convention, in many of the world's legal systems.
A citizen's arrest is an arrest made by a private citizen – that is, a person who is not acting as a sworn law-enforcement official. In common law jurisdictions, the practice dates back to medieval England and the English common law, in which sheriffs encouraged ordinary citizens to help apprehend law breakers.
False arrest, unlawful arrest or wrongful 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.
The judicial system of Israel consists of secular courts and religious courts. The law courts constitute a separate and independent unit of Israel's Ministry of Justice. The system is headed by the President of the Supreme Court and the Minister of Justice.
A perp walk, walking the perp, or frog march, is a practice in law enforcement of taking an arrested suspect, usually right after arrest, out in public, usually from the police station to the vehicle to the courthouse and then after the court hearing back to the vehicle, creating an opportunity for a media frenzy to take photographs and video of the event. The defendant is typically handcuffed or otherwise restrained, and is sometimes dressed in prison garb. Within the United States the perp walk is most closely associated with New York City. The practice rose in popularity in the 1980s under U.S. Attorney Rudolph Giuliani, when suspects charged with felonies were perp-walked.
In the law of criminal evidence, a confession is a statement by a suspect in crime which is adverse to that person. Some secondary authorities, such as Black's Law Dictionary, define a confession in more narrow terms, e.g. as "a statement admitting or acknowledging all facts necessary for conviction of a crime," which would be distinct from a mere admission of certain facts that, if true, would still not, by themselves, satisfy all the elements of the offense. The equivalent in civil cases is a statement against interest.
Actual innocence is a special standard of review in legal cases to prove that a charged defendant did not commit the crimes that they were accused of, which is often applied by appellate courts to prevent a miscarriage of justice.
"Stop and identify" statutes are laws in several U.S. states that authorize police to lawfully order people whom they reasonably suspect of committing a crime to state their name. If there is not reasonable suspicion that a person has committed a crime, is committing a crime, or is about to commit a crime, the person is not required to identify himself or herself, even in these states.
In law, rendition is a "surrender" or "handing over" of persons or property, particularly from one jurisdiction to another. For criminal suspects, extradition is the most common type of rendition. Rendition can also be seen as the act of handing over, after the request for extradition has taken place.
A crime scene getaway is the act of departing from the location where one has commited a crime. It is an act that the offender(s) may or may not have planned in detail, resulting in a variety of outcomes. A crime scene is the "location of a crime; especially one at which forensic evidence is collected in a controlled manner." The "getaway" is any escape by a perpetrator from that scene, which may have been witnessed by eyewitnesses or law enforcement.
In eyewitness identification, in criminal law, evidence is received from a witness "who has actually seen an event and can so testify in court".
Pre-trial detention, also known as preventive detention, provisional detention, or remand, is the process of detaining a person until their trial after they have been arrested and charged with an offence. A person who is on remand is held in a prison or detention centre or held under house arrest. Varying terminology is used, but "remand" is generally used in common law jurisdictions and "preventive detention" elsewhere. However, in the United States, "remand" is rare except in official documents and "kept in custody until trial" is used in the media and even by judges and lawyers in addressing the public. Detention before charge is referred to as custody and continued detention after conviction is referred to as imprisonment.
Welsh v. Wisconsin, 466 U.S. 740 (1984), was a 1983 case before the US Supreme Court determining that a warrantless home arrest without exigent circumstances violates the Fourth Amendment protection against unlawful search and seizure.
The powers of the police in Scotland, as with much of Scots law, are based on mixed elements of statute law and common law.

Sexual violence is defined as the use of force or manipulation to get someone to engage in unwanted sexual activity without his or her consent. Such violence takes place in both heterosexual and homosexual relationships, as well as outside intimate relationships. All sexual offenses violate the basic right of sexual self-determination. In Finland, sexual violence and taking advantage of a person is always a crime, even if the assaulter was the victim's spouse, relative or their friend. Sexual offences include but are not limited to rape, forcing someone into a sexual act and taking sexual advantage of a person. The victims of sexual violence are predominantly women, but 26 percent of Finnish men have experienced sexual harassment since their 15th birthday.
