Are there any laws against either excessively loud motorcycles or riding such motorcycles inconsiderately in residential areas at night? Loud disturbing motorcycles are awful but occasionally circle around certain roads after midnight up and down gratuitously if the objective is actually transportation. One would hope that there are laws on the books restricting the legality of such terribly loud machines in the first place, as a great portion of their appeal appears to be the disturbance caused to others, but if there are not, what is the status of riding them gratuitously at indecent hours? The public (neurological) health hazard is indeed great.
It’s illegal to modify the exhaust system to make a vehicle noisier after it has been ‘type approved’ (checked it meets environmental and safety standards). The police can also take action if your vehicle’s silencer doesn’t work in the way it was designed or if you’re driving in a way that creates too much noise. https://www.gov.uk/noise-pollution-road-train-plane
It may depend on the jurisdiction (although I can't readily think of one where this is not the case) but deliberately, recklessly or negligently putting a burning object next to someone else's property knowing that there is a real risk of it catching fire (and going ahead with it anyway) will almost definitely make one liable: especially if there is an ulterior motive. In england-and-wales This would be called arson - causing criminal damage by fire - an offence contrary to section 1(3) of the Criminal Damage Act 1971 Cross posted with the jurisdiction defining comment
Huge difference between a car and a house. For example, at least in Pennsylvania no warrant is required to search a vehicle on public roads. In other states there are so many easy pretexts that you practically have little protection from a full vehicle search (although the pretext will have to withstand strict scrutiny if evidence found in a search is used to charge you with a crime). Your house, on the other hand, still enjoys very strong fourth-amendment protections: One of my favorite U.S. Supreme Court cases on the subject is Florida v. Jardines, in which SCOTUS ruled that even approaching the front door with a drug-sniffing dog without a warrant constituted an illegal search. (The majority opinion is worth reading for its illumination of current law on this question.)
From a comment on the question: They did damage the trailer door and headlight is smashed This seems like the best thing to focus on, especially if you can show that it was not damaged before they towed it. The unusual method of towing (with video evidence) may be a factor in whether they are considered negligent. If the damage to the door looks like they caused it directly by breaking in, that would also help your case. You also asked in your comment if you should go to the police or to a lawyer first. Might as well go to the lawyer and see what they tell you to do. I'm not sure what the police would do if there is no clear crime that has been committed. (The lawyer should have better advice about whether/why to go to the police.)
The legal hook is reported to be §129 of the Code of Criminal Procedure, which authorizes use of force to disperse an illegal assembly, which this sort of is. No statute that I can find states that police can smack lawbreakers who are forced to disperse, but as is common in common law countries, the laws of India are not fully explicit on that which is allowed or forbidden for police to do. As this article indicates, systematic limits on police use of force remain to be developed.
Courts, particularly traffic courts, tend to take a police officer's word over that of an accused person. While legally the limit is 70, the driver has very little recourse if the officer claims falsely that the actual speed was over 70. But the deterant effect of a posted limit is lost, since drivers in general have no way to know that Officer O will ticket anyone going over 60. I suppose that driver D, or D's lawyer, could subpoena calibration records of any radar gun or other measuring devise used, and could insist on its being tested. However, unless they had reason to think there was an issue, I wonder if D and D's lawyer would go through that process. Some speed measuring devices print a paper slip showing the date and time along with the reading. If such a device was used that record would be harder to alter. Some cars are now equipped with devices provided by insurance companies that record speeds and other driving info in a secure way to help judge a driver's safety and allow individual rate setting. It might be that the record from such a device would be admissible to show the speed was under the posted limit. But there is a sense in which the law is what the police and the courts enforce. If anyone who drives the road over 60 is cited and must pay, one could say the effective limit there is 60.
California Penal Code 647f states that being intoxicated in public is prohibited. When the police arrived, they were confronted with probable cause for an arrest. They (presumably) became aware of the matter because the doctor called the police, since she believe that you would drive drunk. (We can inquire into whether that was a reasonable belief, but it doesn't matter, what matters is that she had the belief and acted on it). Now the question is whether the doctor acting on the belief (making the call) was legal. A negative answer does not affect the legality of the arrest. There is also a law imposing on medical professionals a duty to report, which is fairly wordy, but does not seem to directly require reporting the fact that a person is publicly intoxicated. However, attending circumstances could have suggested one of the triggering causes for mandatory reporting (wounds, for example). Again, it does not matter (to a point) if, in the light of close scrutiny, the doctor's conclusions were mistaken. When doctors are required to report facts to the police, reasonable over-reporting is not penalized. There is also no law against calling 911 to report a potential DUI (the usual public-campaign focus is on those actually driving). So calling the police under the circumstances falls between "allowed" and "required". The HIPAA privacy rule could be relevant because that theoretically could block the doctor from making the call. (Note that the doctor, and not the patient, is bound by the confidentiality requirements). §160.203 allows exceptions to the confidentiality requirement if "necessary... For purposes of serving a compelling need related to public health, safety, or welfare", so an exception may have been granted. If this was done within the scope of a mandatory reporting law, it is legal to disclose PHI; under §164.512 it is allowed, "to prevent or lessen a serious and imminent threat to the health or safety of a person or the public". A confidentiality agreement would not increase your chances of being arrested. If the doctor's confidentiality statement were less restrictive than HIPAA, HIPAA prevails (the law trumps contract terms). If it is the same as HIPAA, it has no effect (and simply states what HIPAA says – the normal case). If the agreement were more restrictive, it is possible that the doctor calling the police would be a breach of contract, unless the call was required by law. You would have to see what in the agreement would have prohibited calling the police. But that would not affect the validity of the arrest. To re-phrase the matter: the arrest was because you were found to be intoxicated in public. The police were there and could judge your state (probable cause). They were there by permission of the property owner, so the arrest was not unlawful for lack of a warrant. That is as far as one can go in searching for an illegality to the arrest itself. One might go further and ask whether the doctor has committed an actionable wrong by calling the police with her suspicions. This could go either way: it really depends on the full set of details, regarding your condition. If the doctor suspected that your actions fell under one of the mandatory reporting categories, she had to report, and otherwise it is not prohibited under HIPAA. If a person is intoxicated and answers the question "Would you normally proceed to drive home in this state?" in the affirmative, then it is a reasonable inference that the person will do so. An answer "No, absolutely not", on the other hand would work against the "public danger" inference: that has no effect on the arrest, but could have an effect in a suit against the doctor (violation of the privacy rule). In such a suit, the doctor's defense would presumably be that despite the answer, she still had a reasonable belief that you were a public danger. Then the matter would reduce to what other facts she knew of that would support a public danger conclusion.
In New York State, vehicle registration requirements (including the requirement to display license plates) are under Title IV of the Vehicle and Traffic Law. Title IV refers to "motor vehicles." However, Section 125 of the law, which defines "motor vehicle" for the purposes of the law, states that: Every vehicle operated or driven upon a public highway which is propelled by any power other than muscular power [...]. For the purposes of title four of this chapter, the term motor vehicle shall exclude fire and police vehicles other than ambulances. [...] Fire and police vehicles in New York State are exempt from registration requirements, including the requirement to have a license plate. They can use license-plate-esque designs, and I believe they can get normal local government plates, but they do not have to. EDIT: Also, I just remembered the NYPD operates at least one ambulance. Per that section, one would expect the ambulance to use a state-issued license plate, not the NYPD fleet plates. And this is, in fact, the case:
