When is a web-site owner obligated to report a crime? Suppose someone operates a web-based forum where users can post information for other users to view. While not a mandated reporter as defined by the state the operator lives in, the site users come from different parts of the United States and some from other countries. Would the operator be obligated to report a crime or suspected abuse which is posted by a user to law-enforcement agencies? If so, what criteria should be used to determine which agency or agencies they should report to?
It may depend on what offences are suspected of being committed. One example is: In the united-states under 18 U.S. Code § 2258A an Electronic Service Provider (ESP) is required to report apparent violations of sections: 2251 [Sexual exploitation of children] 2251A [Selling or buying of children] 2252 [material involving the sexual exploitation of minors] 2252A [material constituting or containing child pornography] 2252B [Misleading domain names with intent] 2260 [sexually explicit depictions of a minor etc] The report is made to the National Center for Missing &amp; Exploited Children (NCMEC) who in turn forward the information to the relevant domestic or foreign law enforcement agency. The ESP is protected from commiting distribution or related offences when making the report by virtue of subsection (g)(4): Permitted disclosure by a provider.— A provider that submits a report under subsection (a)(1) may disclose by mail, electronic transmission, or other reasonable means, information, including visual depictions contained in the report, in a manner consistent with permitted disclosures under paragraphs (3) through (8) of section 2702(b) only to a law enforcement agency described in subparagraph (A), (B), or (C) of paragraph (3), to NCMEC, or as necessary to respond to legal process.
You misunderstand the significance of the phrase "innocent until proven guilty." This is in part because you are not considering the entire phrase. The full phrase is that an accused party is "presumed innocent until proven guilty." This does not mean that the accused is innocent, only that criminal procedure must take as its starting point that the accused did not commit the crime. The major implication of the presumption, and indeed its original purpose, is that it places the burden of proof on the prosecution. This means that if a prosecutor asserts that you stole something, you do not have to prove that you did not. Rather, the prosecutor must prove that you did. The only reason to present evidence of your own is to rebut the prosecutor's evidence. Another practical implication is that a decision to detain someone awaiting a criminal trial may not be based on the assumption that the accused committed the crime. On the other hand, that decision is not based on the assumption that the accused did not commit the crime. There is a presumption of innocence, but no assumption of innocence, and the government is not obliged before the person is convicted to treat the person as if there is no accusation or charge. Wikipedia has a decent discussion. If we modify your question accordingly, it becomes How can two people be presumed innocent until proven guilty if their stories conflict? Now the answer should be clear. The prosecutor must develop evidence that shows which one of the people has committed the crime. If the prosecutor cannot do that, neither person may be punished.
Police have discretion in the enforcement of the law Which is to say, police get to decide which crimes they make arrests for, which they handle with warnings, which they report and which they ignore. This applies whether they are in uniform, undercover or off-duty. If they abuse this discretion then they are liable to disciplinary action. If they apply it corruptly or otherwise illegally then they are liable to criminal sanction.
Police officers are authorized to use force regardless of what they are wearing, to effect an arrest. One issue will be whether the defendants should know that they were under arrest, but there is no requirement to utter particular phrases when dealing with a combative lawbreaker. There will be an internal investigation at some level to determine whether the officers violated any department policy, and no doubt the video and testimony of those in the are would be relevant. There probably is some policy to the effect that you have to distinguish yourself from a street vigilante (you have to state your authority), though I can't find any specific online publicly-available department rules. There is no law that requires an officer to say that he is one, or to show his badge, before starting an arrest.
In the United States who has the authority and what is the procedure to determine if conduct by an individual is "illegal"? You are conflating several different ideas here, which is probably the source of your persistent confusion. 1) Actions are legal or not Illegal: Not authorized by law; Illicit ; unlawful; contrary to law The law sets out certain things that you must do (you must stop at a red light) and things you must not do (you must not drive under the influence). Sometimes actions fall into a gray area of the law, or aren't addressed at all, but if something is spelled out, then it's very clear whether the abstract action is legal or not. Running a red light is illegal. Driving under the influence is illegal. There are definitions and specified penalties for both. 2) A person may or may not be guilty of an illegal action Guilty: Having committed a crime or tort Abstract actions can be legal or illegal, but people commit crimes. When someone commits a crime, they are guilty of that crime. This is true whether or not they are ever prosecuted, or even if law enforcement knows who the guilty one is. If someone runs a red light at 2 in the morning on an empty street, it's still illegal and thus they are guilty of running a red - but no one will ever catch them. If someone is shot in the middle of the street, then someone is guilty of shooting them. Again, the shooter may never be found, but whoever they are, they are still guilty. 3) An individual may or may not be guilty of the crime of which they are charged. Charge: the statement of the alleged offense that brings a person to court If law enforcement (whether your local traffic cop or the FBI) believes that you are guilty of a crime, they can charge you with committing it. They may be right. They may be wrong. But the suspicion of having committed it is enough to charge you. To continue the traffic example: If an officer sees you running the red light, they can write you a ticket (effectively charging you) for doing so. They may or may not actually be right (it could have been yellow or malfunctioning, for example), but law enforcement has the power to charge regardless. 4) A defendant may or may be found guilty and convicted. Conviction: In a general sense, the result of a criminal trial which ends in a judgment or sentence that the prisoner is guilty as charged. Finding a person guilty by verdict of a jury. This is where the presumption of innocence comes in - the default assumption is that the accused did not commit the crime that they are being charged with, and it's the prosecutor's job to prove otherwise. If the accused is found to not be guilty of the crime, then they (presumably) didn't do it - it doesn't necessarily mean the crime didn't happen, just that this specific person didn't commit it. Alternatively, the defendant can be found not guilty for other reasons - the judge or jury can determine that the crime didn't take place, took place but was justified, or the defendant wasn't in their right mind at the time. On the other hand, if they are found guilty, they're convicted and sentenced to whatever an appropriate punishment is. TL;DR Whether something is legal is determined by the legislature when they pass laws. Someone who commits an illegal act is guilty of doing so, even if they are never charged. Again, this is determined by the legislature when they pass laws. People are charged with violations of specific laws by law enforcement. Defendants can be found guilty by the court system. In other words, only the courts can determine whether a specific individual actually committed illegal behavior, but the behavior is still illegal regardless.
Section 230 (of Title 47) grants immunity from civil liability under certain circumstances, so the website is not liable to the porn-distributor for taking down their images. There are also criminal laws pertaining to child porn, such as 18 USC 2252. It is not a crime to &quot;see&quot; child porn. Instead, the crime is defined with reference to one who knowingly receives, or distributes, any visual depiction... of child porn. Therefore you cannot be prosecuted if you do not know that the image is has the prohibited characteristics (is child porn). See US v. X-Citement Video, 513 U.S. 64 for discussion of th scienter requirement. The surrounding circumstances (the report) at most indicate that the moderator has some reason to believe that it is porn, and the immediate deletion of the material supports the conclusion that the moderator's action complies with the law. Paragraph (c) of that law also provides a defense, in case of prosecution: It shall be an affirmative defense to a charge of violating paragraph (4) of subsection (a) that the defendant— (1) possessed less than three matters containing any visual depiction proscribed by that paragraph; and (2) promptly and in good faith, and without retaining or allowing any person, other than a law enforcement agency, to access any visual depiction or copy thereof— (A) took reasonable steps to destroy each such visual depiction; or (B) reported the matter to a law enforcement agency and afforded that agency access to each such visual depiction.
The police only get involved with criminal matters. So when your question assumes police involvement, the logical conclusion is the host parents allegedly committed some crime. If that were the case, let's say the crime were something like child abuse, criminal negligence or abandonment of a minor. Then the prosecutor's office and/or CPS (Child Protective Services) would do an investigation and, if warranted, refer the matter to the jurisdictional prosecuting attorney's office who could file criminal charges and pursue a prosecution.
You are referring to Michigan State Police v. Sitz 496 U.S. 444 (1990). It does not require or suggest a requirement of advance publication of any details regarding the checkpoints. The dissent mentions that "a sobriety checkpoint is usually operated at night at an unannounced location. Surprise is crucial to its method." This point was not countered or even mentioned by the majority. In this case, a state committee had created guidelines setting forth procedures governing checkpoint operations, site selection, and publicity. The mentions this as a background fact, but does not rely on the existence of these guidelines as a requirement for the constitutionality of checkpoint stops. It does contrast checkpoints with "roving patrol stops". Quoting from Martinez-Fuerte 428 U. S. 543 (1976), the majority in Sitz said: "at traffic checkpoints, the motorist can see that other vehicles are being stopped, he can see visible signs of the officers' authority, and he is much less likely to be frightened or annoyed by the intrusion". There are state guidelines, some states have constitutions prohibiting sobriety checkpoints (lots of case law at the state level regarding this), and some state legislatures have made these illegal. In Sitz, the checkpoints were being operated subject to guidelines developed by the Sobriety Checkpoint Advisory Committee (of the State Department of Police). Federally, the NHTSA has guidelines on visibility and publicity towards the goal of effectiveness.
