What is the legal status of hentai Japanese visual novels and manga in the US depicting minors? My common sense says no. If someone took a piece of paper and a pencil and drew some very detailed pictures of 2D anime people. It feels insane that that would be enough to constitute felony possession. This entire wikipedia list suggest otherwise: https://en.wikipedia.org/wiki/Legal_status_of_cartoon_pornography_depicting_minors#18_USC_1466A where it looks like several individuals were convicted only on the possession of drawings. Certainly, if an artist is using technology to image real minors into his artwork, then that would be a common sense violation of the law. But that doesn't appear to be the case. Clearly there must be some line separating safe and illegal between the extreme examples.
One relevant US law is Title 18 Chapter 110. Using real children in porn is against the law, as is most anything connected to it (permitting children to do it, distributing, buying...). Under the definitions (18 USC 2256(1)) “minor” means any person under the age of eighteen years. The possible hook for cartoons is via the definition of “child pornography” which is any visual depiction, including any photograph, film, video, picture, or computer or computer-generated image or picture, whether made or produced by electronic, mechanical, or other means, of sexually explicit conduct, where— ... (B) such visual depiction is a digital image, computer image, or computer-generated image that is, or is indistinguishable from, that of a minor engaging in sexually explicit conduct; or (C) such visual depiction has been created, adapted, or modified to appear that an identifiable minor is engaging in sexually explicit conduct. My guess is that hentai doesn't satisfy this definition, since I hear that the characters in a cartoon don't actually look like real people. However: there are also general laws against obscenity in some jurisdictions, and in US v. Whorley, it was held that you can still be convicted of receiving obscene material (Japanese child porn cartoons) – SCOTUS refused to hear an appeal. Most cases that are prosecuted also involve real child porn, or plea bargaining. In light of Whorley, it hasn't been definitively determined that hentai is against the law, but the first step has been taken.
Yet I publicly wear shirts with copyrighted designs all the time. I'm unclear about this; do you mean T-shirts you have made yourself using copyrighted images or T-shirts you have bought? If the former then it is a prima facie breach and you could be sued by the copyright holder. You would probably not be as it would be impracticable. If the latter then there are 2 possibilities: The manufacturer/distributer/retailer chain all hold valid licences to put the image on a T-shirt and display it in the usual way so there is no breach involved. The manufacturer/distributer/retailer chain does not hold a valid licence in which case there is a breach and the copyright holder would target, say Wall-Mart rather than you. what about displaying ... works of art in my yard? Notwithstanding that it can be viewed from a public space, your yard is not public; therefore this is not public display.
In general, using content provided by another who incorrectly posted it under a permissive license, such as a CC license, does not grant a valid license from the real copyright holder. That is, if A writes some code (or a song, or creates an image, or whatever else), it is protected by copyright. If B then posts it to the web, with a statement that it is released under a particular license, without having obtained permission from A, then B's &quot;release&quot; is of no value, because B had no rights to grant. If C downloads and uses this content, relying on B's license, then A could take legal action against C. C would probably be considered (in the US) an &quot;innocent infringer&quot; which reduces the minimum statutory damage amount, but does not otherwise change C's legal position. A could, if it chose, bring suit and possibly obtain a judgement including some damages. But to return to the practical case of code posted on one of the SE sites. Given the comparatively short code sections usually posted, and that they do not usually form a complete working program, and given further the stated educational purpose of SE, it is likely that in US law such a posting would constitute fair use, and in the law of other countries fall under one or another exception to copyright. That is a general conclusion, the details would matter. I have not heard of a case similar to that suggested in the question. I find it unlikely that an SE poster would post copyright-protected code without permission, that is valuable enough to be worth an infringement suit, and substantial enough and having enough effect on th market for the original to be outside the protection of fair use. Such a situatiion is, of course, possible, even if unlikely. Note that a cease-and-desist letter is not a court order, and is really only a threat of court action. its only legal effect is to put the recipient on notice, so that continued infringement is not without awareness of the copyright claim. To have legal effect the claimant must actually bring an infringement suit, which is not without cost.
You don't seem to be distinguishing properly between "original artwork" and photographs of it. A 19th-century painting will be out of copyright, so you can set up an easel copy it yourself, or even take a photo if the owners don't mind; your copy can be used however you please. However, other people can't use your photograph without your permission. Similarly, if you want to reuse a photograph used in an art book, the important thing is the copyright on the photograph, not the painting.
Jurisdiction: Ohio. What charges might this kid face? Let's deal with each individually. Possession of Child Pornography Based on the facts contained in your narrative, the suspect is guilty of possession of child pornography. Here is the relevant code statute. (2907.323 Illegal use of minor in nudity-oriented material or performance.) There might or might not be a problem with the admissibility of the evidence under the circumstances. This defect can be cured if the prosecution obtains a search warrant for the suspect's computer as possession alone meets the statutory threshold. Aggravated Robbery In Ohio, aggravated robbery is not a strict liability (i.e., statutory) crime. Therefore, mens rea (mental state) of the offender can be a legal defense. In this case, the suspect can argue duress as an exculpatory and/or mitigating factor. Here is the relevant code section. Murder As you pointed out in your narrative, the facts suggest the suspect killed in self-defense and, therefore, is not guilty of murder.
Photographs of objects other than flat artworks, including pretty much all the things you list except in some cases oil paintings, involve creativity and originality in composition, positioning, lighting, and other aspects, and each such photo would be copyrighted by the photographer (or the photographer's employer in a work-made-for-hire situation). Such photos (or copies of them) could be sold if the copyright owner chooses to, just like any copyrighted work. If the object being photographed is itself a work of art, and if it is recent enough that it is still under copyright protection (See this chart for US rules on copyright terms), then the photo would be a derivative work, and the permission of the copyright holder on the original would in theory be required. But such a requirement could only be enforced by the copyright holder on the original work filing suit, and if the work is not clearly identifiable this might not be likely. If the photographer knows the name of the original artist, and the work seems likely to be still in copyright, an attempt to secure permission would be at least good practice, and quite possibly legally essential. For a flat (2D) work of art, such as a painting, if the photo attempts to reproduce the original exactly (a "slavish copy" ), then under the Bridgeman Art Library v. Corel Corp., 36 F. Supp. 2d 191 (S.D.N.Y. 1999) decision, the photo will not be original and so will not be protected by copyright. See this question and its answers for more on Bridgeman A photo of a painting on a stand, showing the painting and its frame, and not trying to just reproduce the painting exactly, will not fall under the Bridgeman rule. This answer is quite US-oriented. Much of it will apply in any country which adheres to the Berne Copyright Convention but the details may vary, and if a different jurisdiction is intended, that should be stated.
If I lock you in a room without access to anything and tell you &quot;Write a novel&quot; and you write a novel with characters, you have copyright in the work. But it's not absolute: If you use your own characters, you own all the copyright in the work, but not in the idea, as ideas are not copyrightable, see Feist v Rural. If you use someone else's characters extensively (as in more than a short hommage/cameo), you very likely make a derivate. You own a copyright in your part, as in the expression of the story or pictures you created, but you do not gain property interest in the existing characters' expression. Since the copyright to the characters lies with the owner of their IP, you need their OK to release (and also to even make) your work - as with the owner of a copyright is the sole right to decide on distribution and creation of derivates under 17 USC § 106 (2). Also remember that making an unlicensed derivate work risks having nothing you can sue for in case the original copyright owner lifts your ideas and scenes-a-faire parts and adapts them for their own derivate, see Anderson v Stallone The strange case of fanfiction chains... Now, there is a strange situation when a work is based on a work which is based on a work... Then, publishers and editors start with red ink and the result is, that what people know as Twilight now has nothing to do with the fanfiction it started as (It wasn't Vampires in the original draft), and 50 Shades of Grey ended up striking any and all supernatural from it, despite it having been a Twilight fanfiction originally. By making own characters and own expression of the world, there could be no copyright infringement. US law vs Egypt law? Both Egypt and the US have signed the Berne convention, meaning that copyright is very very similar in the broad strokes that the right to allow or disallow derivates is with the copyright holder. Also, since Ben10's copyright owners are to the best of my knowledge in the US (Cartoon Network Studios &amp; Men of Action Studios), they will sue in a US federal court.
In NSW Australia this is covered by Division 15A of the Crimes Act 1900 which deals with Child Abuse Material. Under Section 91FA a &quot;child&quot; means a person who is under the age of 16 years - the situation you describe would be between consenting adults in NSW. “Child abuse material” can be text or images that are sexually explicit and would be “offensive” to a normal person (which means offensive to the particular jury) Assuming Jane is 15 or less, however, prima facie the image would be child abuse material and under Section 91H &quot;A person who produces, disseminates or possesses child abuse material is guilty of an offence.&quot; The punishment is up to 10 years in jail. Section 91H provides a number of defences, the most relevant to the circumstances you describe being: that the defendant did not know, and could not reasonably be expected to have known, that he or she produced, disseminated or possessed (as the case requires) child abuse material. that the material concerned came into the defendant’s possession unsolicited and the defendant, as soon as he or she became aware of its nature, took reasonable steps to get rid of it. (for possession only) If, considering all the circumstances of the relationship, Joe doesn't know and could not reasonably be expected to know Jane's age then he can use the defence under S91H(1). If he did not request the picture and as soon as he was aware of Jane's age, deleted it, then he can use the defence under S91H(2). The outcome is not so rosy for Jane: she is guilty of both production and dissemination of child abuse material and (assuming she knows how old she is) faces up to 10 years in jail (14 if she is under 14) and registration on the Sex Offenders List for life. It is admittedly unlikely in the circumstances that the state would prosecute her and, if they did, it is very likely that the judge would rule that no conviction be recorded.
