USA: Is it legal to take naked non-abusive pictures of my child? I was wondering if it's illegal to take pictures of a baby while he's naked, for example. I'm mostly asking for babies, but it would be nice to know what age is ok to do it.
Yes, it's legal. To be illegal, the photographs would have to be obscene or pornographic. Nude people, ordinarily photographed, doing non-sexual, non-excretory things are neither. However, I would strongly advise caution, particularly if you plan to display or share these photographs. There are definitely cases of people who have been charged with sexual exploitation of a minor for sharing nude photographs of their children.
According to the ACLU, in the U.S.: Taking photographs and video of things that are plainly visible in public spaces is a constitutional right—and that includes police and other government officials carrying out their duties. I.e., a law enforcement officer can never lawfully demand that you turn off a recording device. However the ACLU itself acknowledges that this right continues to be broadly infringed by government agencies and agents. The ACLU and other watchdog groups try to document and fight infringements of this right. Infringement is still so widespread that, in practice, there are many areas and circumstances in which you could expect to be detained, harassed, arrested, and even charged with various crimes for recording police, or for refusing police demands to stop recording. (The charges will not be for recording police, since that is not a crime, but will typically be "contempt of cop" type charges like obstruction, failure to obey, assault, resisting arrest, etc.)
The fact that something is illegal does not imply that it is illegal to post pictures of it happening. In general, under U.S. law, free speech protects almost all forms of communications subject to a handful of narrow exceptions and this is not one of them. There are many legitimate reasons one might want to post video of a fight (e.g. to identify crime perpetrators for purposes of prosecuting them), but no legitimate purpose is legally necessary. Surely as a platform Reddit cant hide against it being a platform of free speech in this case? They most definitely can. Reddit is also not responsible for user posted content under Section 230 of the Communication Decency Act, even if it were illegal for the person posting it to post the content
If she was under 16, it's rape. A child under that age cannot consent to intercourse. If she's older, it may still be sex abuse, which includes subjecting a person to sexual contact without express or implied consent. It may also still be rape, but I'm less clear on how Kentucky courts define implied consent.
Are there actual laws written, or de facto situations (e.g. let's say another law specifies that a child can't be physically forced to go anywhere without causing abuse) where the child can refuse to attend? Are there "tiers" to the age; Is it true that a temper tantrum of a 5 year old would be seen as such, but the refusal of a 17 year would be legally accepted? This is a hard question to answer that doesn't have a neat resolution. Very little pertaining to the authority of a parent over a child is codified in statutory law and there is not a clear cut age at which a child has "freedom of conscience" vis-a-vis a parent. Most of the law related to children concerns allocation of parenting time and parental decision making between divorced, separated or unmarried parents; abuse and neglect; and juvenile delinquency. There is also usually a snippet of criminal law stating that certain kinds of uses of force to discipline children do not constitute crimes. But, part of why it doesn't come up very much is that older children are usually socialized in a manner that causes them to show a certain amount of respect for the wishes of their parents. It also doesn't come up much for children who aren't in their late teens, because the complete economic dependence of children on their parents or guardians gives the parents considerable power of their children that doesn't require the exercise of physical force. Also, it is quite dependent upon how the issue presents itself. No law enforcement agency is going to aid a parent in forcibly dragging a kid to church against their will. But, no social services agency is going to remove a kid from a home because his birthday party will be cancelled if he doesn't go to the church of his parents' choice the Sunday before his birthday. There are also some subtle but important distinctions between states on the issue of emancipation. In Colorado, emancipation is a statement about the empirical reality. If a child is self-supporting and lives apart from parents or guardians then the child is an emancipated minor. It is not a status granted by a court, it is a status acknowledged by courts when evaluating other issues. In California, a child is not emancipated unless a court grants a child that status and a child who is de facto emancipated without the leave of a court is guilty of a "status offense" (the New York State term for someone in this state is PINS for "person in need of supervision"). Basically, if a parent can force a child to go to church by means that don't constitute abuse or neglect and don't exceed the level of force authorize for child discipline in the criminal code, then they can do it, and if they can't manage that, then they can't do it. Many states have a "status offense" that allows government intervention with the cooperation of a parent or guardian in cases where an "uncontrollable" child is defiant and simply will not give any heed to the parent or guardian's instructions. In practice, the older a child is, the less likely someone viewing a parent's conduct forcing a child to do something is to be viewed as acceptable or legally justified. The legal rights of children in a school setting are also age dependent under the case law, although not always in a really well defined way. Controls on student expression that would be uncontroversial for elementary school students may be looked upon by the law with disfavor for high school students and clearly prohibited for adults. Perhaps one useful way to conceptualize it is that trying to make a child attend a particular kind of religious service is not considered an improper purposes for a parent of any minor to utilize the resources available to the parent to do so, but the range of resources available to a parent with regard to an adult child is much narrower.
I'm just asking what the legality is for parents to vaccinate their children against rabies if they were bitten by an animal. Also, would legal implications change if the animal that bit the child later tested positive for rabies or if the child insists on getting a rabies vaccine but the parent refuses? Can the parent be charged for a crime if the child develops symptomatic rabies and dies? In this circumstance, while a parent has fairly broad discretion, once the necessity of preserving a child's life comes into play and rabies can be deadly, that discretion ends and the child's life takes priority. Failing to do so could constitute child abuse and result in termination of parental rights and criminal sanctions for child abuse causing death or something similar. Simply failing to treat rabies out of good faith ignorance of the option, however, would ordinarily not be a criminal offense.
I think it's important to keep in mind the essence of your actions. @Mowzer gave a great answer on the matter in hand, but I'd like to add a point of view. Is it illegal to eat while driving? Like pointed out by @Mowzer, if no law prohibits it, it's allowed by default (lots of countries have this premise). But what about the consequences of your actions? Maybe there's no law against eating in the car, but there sure is one in my country that specific says that you are not allowed to drive without using both hands in the wheel. The only exception to this rule is to take out your hand from the wheel to use the stick to change gears. Another point of view to add is the liability. Let's say you're minding your own business while driving and a lunatic trying to commit suicide jumps in front of your car. It's a pretty straight-forward case, you have no reason to be blamed. Now, let's add to the same scenario your snack; with a small change, you are now facing a accident that may have been caused by reckless driving (another thing commonly illegal). To sum up, the law is not really like math that have axioms that determine true or false statements without any distinguishment. That's why every case is single handled in the law by it's particularities.
In the US, there are no laws against surgical circumcision with informed consent (and I don't know of any such laws in any other country). Parents are generally allowed to grant surrogate informed consent. There is no requirement that circumcision be carried out by a licensed physician or other approved practitioner. A person can be held civilly liable for damage done by the procedure. There are no criminal prohibitions in the cases that you describe, but there could be civil interventions. In particular, the court could override parental consent – for instance, if a parent ordered circumcision of their 17 year old. If some person does the circumcision without parental consent, that could be a crime. The key distinction is parental consent. The law grants parents the power to act on behalf of the child, under the premise that children do not have the capacity to act in their own best interest, and cannot reasonably be forced to bear the full consequences of their actions. These are long-standing pre-common law premises, which even predate the promulgation of English common law. "Best interest" is not a technical term requiring definition, but it is a factual matter that is very difficult to judge. Judges use solomonic wisdom to determine whether a surgery is in the best interest of a child when it is medically advantageous but psychologically detrimental. Just as an adult can consent to a circumcision thereby negating any accusation of assault, so too can a parent consent on behalf of their child.
