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."
Cohen v. California, 403 U.S. 15 (1971), was a landmark decision of the US Supreme Court holding that the First Amendment prevented the conviction of Paul Robert Cohen for the crime of disturbing the peace by wearing a jacket displaying "Fuck the Draft" in the public corridors of a California courthouse.
Hiibel v. Sixth Judicial District Court of Nevada, 542 U.S. 177 (2004), is a United States Supreme Court case in which the Court held that a statute requiring suspects to disclose their names during a valid Terry stop does not violate the Fourth Amendment if the statute first requires reasonable suspicion of criminal involvement, and does not violate the Fifth Amendment if there is no allegation that their names could have caused an incrimination.
Breach of the peace or disturbing the peace, is a legal term used in constitutional law in English-speaking countries and in a public order sense in the several jurisdictions of the United Kingdom. It is a form of disorderly conduct.
Reasonable suspicion is a legal standard of proof in United States law that is less than probable cause, the legal standard for arrests and warrants, but more than an "inchoate and unparticularized suspicion or 'hunch'"; it must be based on "specific and articulable facts", "taken together with rational inferences from those facts", and the suspicion must be associated with the specific individual. If police additionally have reasonable suspicion that a person so detained is armed and dangerous, they may "frisk" the person for weapons, but not for contraband like drugs. However, if the police develop probable cause during a weapons frisk, they may then conduct a full search. Reasonable suspicion is evaluated using the "reasonable person" or "reasonable officer" standard, in which said person in the same circumstances could reasonably suspect a person has been, is, or is about to be engaged in criminal activity; it depends upon the totality of circumstances, and can result from a combination of particular facts, even if each is individually innocuous.
Forsyth County, Georgia v. The Nationalist Movement, 505 U.S. 123 (1992), was a case in which the United States Supreme Court limited the ability of local governments to charge fees for the use of public places for private activities. By a 5–4 vote, the court ruled that an ordinance allowing the local government to set varying fees for different events violated the First Amendment due to the lack of "narrowly drawn, reasonable, and definite standards" governing the amount of the fee.
Virginia v. Black, 538 U.S. 343 (2003), was a landmark decision of the Supreme Court of the United States in which the Court held, 5–4, that any state statute banning cross burning on the basis that it constitutes prima facie evidence of intent to intimidate is a violation of the First Amendment to the Constitution. Such a provision, the Court argued, blurs the distinction between proscribable "threats of intimidation" and the Ku Klux Klan's protected "messages of shared ideology". In the case, three defendants were convicted in two separate cases of violating a Virginia statute against cross burning. However, cross-burning can be a criminal offense if the intent to intimidate is proven. It was argued by former Solicitor General of Virginia, William Hurd and Rodney A. Smolla.
"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.
Brigham City v. Stuart, 547 U.S. 398 (2006), is a United States Supreme Court case involving the exigent circumstances exception to the Fourth Amendment's warrant requirement. The Court ruled that police may enter a home without a warrant if they have an objectively reasonable basis for believing that an occupant is or is about to be seriously injured.
In the United States, open carry refers to the practice of visibly carrying a firearm in public places, as distinguished from concealed carry, where firearms cannot be seen by the casual observer. To "carry" in this context indicates that the firearm is kept readily accessible on the person, within a holster or attached to a sling. Carrying a firearm directly in the hands, particularly in a firing position or combat stance, is known as "brandishing" and may constitute a serious crime, but is not the mode of "carrying" discussed in this article.
In the United States, a no-knock warrant is a warrant issued by a judge that allows law enforcement to enter a property without immediate prior notification of the residents, such as by knocking or ringing a doorbell. In most cases, law enforcement will identify themselves just before they forcefully enter the property. It is issued under the belief that any evidence they hope to find may be destroyed between the time that police identify themselves and the time they secure the area, or in the event where there is a large perceived threat to officer safety during the execution of the warrant.
Kolender v. Lawson, 461 U.S. 352 (1983), is a United States Supreme Court case concerning the constitutionality of vague laws that allow police to demand that "loiterers" and "wanderers" provide "credible and reliable" identification.
In the United States, a sheriff is the chief of law enforcement of a county. Sheriffs are usually either elected by the populace or appointed by an elected body.
Ontario v. Quon, 560 U.S. 746 (2010), is a United States Supreme Court case concerning the extent to which the right to privacy applies to electronic communications in a government workplace. It was an appeal by the city of Ontario, California, from a Ninth Circuit decision holding that it had violated the Fourth Amendment rights of two of its police officers when it disciplined them following an audit of pager text messages that discovered many of those messages were personal in nature, some sexually explicit. The Court unanimously held that the audit was work-related and thus did not violate the Fourth Amendment's protections against unreasonable search and seizure.

Gregory v. Chicago, 394 U.S. 111 (1969), was a United States Supreme Court case in which the Court overturned the disorderly conduct charges against Dick Gregory and others for peaceful demonstrations in Chicago.
People v. Aguilar, 2 N.E.3d 321, was an Illinois Supreme Court case in which the Court held that the Aggravated Unlawful Use of a Weapon (AUUF) statute violated the right to keep and bear arms as guaranteed by the Second Amendment. The Court stated that this was because the statute amounted to a wholesale statutory ban on the exercise of a personal right that was specifically named in and guaranteed by the United States Constitution, as construed by the United States Supreme Court. A conviction for Unlawful Possession of a Firearm (UPF) was proper because the possession of handguns by minors was conduct that fell outside the scope of the Second Amendment's protection.
Refusing to assist a police officer, peace officer or other law enforcement officer is an offence in various jurisdictions around the world. Some jurisdictions use the terminology '"refusing to aid a police officer" or "failure to aid a police officer".
Chy Lung v. Freeman, 92 U.S. 275 (1876), was a US Supreme Court case that ruled that the powers to set rules surrounding immigration and to manage foreign relations rest with the US federal government, rather than that of the states. The case has been cited in other Supreme Court cases related to government authority on matters relating to immigration policy and immigration enforcement, most recently in Arizona v. United States (2012).
Elrod v. Burns, 427 U.S. 347 (1976), is a United States Supreme Court decision regarding political speech of public employees. The Court ruled in this case that public employees may be active members in a political party, but cannot allow patronage to be a deciding factor in work related decisions. The court upheld the decision by the 7th Circuit Court of Appeals ruling in favor of the respondent.
