Can someone be convicted with an unwarranted surveillance video? If I were to place recording equipment within someone's home without their consent or a warrant, completely on my own accord and unsanctioned, would I be committing a crime? If I were to record someone committing a crime such as murder or assault with that equipment, would I be able to use that as evidence in court to convict the perpetrator of such wrongdoings?
There is no common law offence of electronically recording a private place/activity, but many jurisdictions have legislation that makes it an offence: e.g. Surveillance Devices Act 1999 (Vic), s 7. Whether evidence collected through illegal surveillance is admissible will depend on the legislation in each jurisdiction. For example, in Victoria, such evidence is inadmissible unless the court decides that admitting the evidence is sufficiently desirable: Evidence Act 2008 (Vic), s 138. This discretion reflects 'the fundamental dilemma... between the public interest in admitting reliable evidence (and thereby convicting the guilty) and the public interest in vindicating individual rights and deterring misconduct and maintaining the legitimacy of the judicial system': Australian Law Reform Commission (2006) 'Uniform Evidence Law', [16.84].
There is no way to know for absolute sure. The statutes do not address the question, so one would look at the case law. There appear to be about a dozen wiretapping cases that made it to the court of appeals in Maryland, and none of them involve implied consent (e.g. where it is announced prior to recording that the call may or will be recorded – prior is mandatory). The probability is high that implied consent suffices, since the legislature did not specific require express consent and consent is not generally taken to mean express consent. One can and should hire an attorney who will give you a professional and considered (but not infallible) opinion, if it really matters.
Theft is of course illegal in all US states, and pretty much every other jurisdiction. In the US that is a matter of state law, not federal. It could be reported to the local police, but it might be hard to prove. Both landlord/tenant law and privacy law are largely matters of state law in the US, not federal law. Such laws vary a good deal in different states. In many states a landlord is allowed to enter the rented premises, usually on "reasonable" notice, or without notice if there is an emergency. If the landlord actually lives in another part of the house, and simply rents a room to the tenant, the landlord may be able to enter the room more freely than if it was a separate apartment or house. In many cases where there is a written lease or rental agreement, it will specify under what conditions the landlord or landlord's agent may enter, and how much notice is required. What does the lease in the current case say about that?
As far as I know, every jurisdiction in America limits perjury to cases of lying under oath. Because it seems unlikely that the driver would be under oath at this point, you would probably lack probable cause to make an arrest. At the same time, many states have separate laws addressing the making of false reports, lying to an officer, etc. I'd imagine most jurisdictions would have a law supporting an arrest for lying at the scene, even if not for perjury.
There are no such laws that are specific to rape, but there are general laws about false statements. In every state there is some law against making a false statement to a government official, e.g. Washington RCW 9A.76.175 which says that one who "knowingly makes a false or misleading material statement to a public servant is guilty of a gross misdemeanor". To shift context slightly, if you report to the police that Smith stole your lawn mower when in fact you gave it to him, that is a false statement. However, there would have to be clear proof that you lied in your report, and not that there was a misunderstanding. If Smith stole the mower but the evidence did not support a theft conviction, that does not mean that you can be prosecuted for making a false statement (whereas, if someone has a video of you telling Smith "Here's a mower, which I give to you because I like you", then you could almost be prosecuted for making a false statement, were it not for the fact that the video is illegal in Washington). Perjury is the other related crime: RCW 9A.72.020 "a materially false statement which he or she knows to be false under an oath required or authorized by law". [Addendum] About the video of the mower being given away... Washington is an all-party consent state, meaning that you can't just record people, you have to have their permission (everybody's permission). RCW 9.73.050 says that information obtained by illegal recording shall be inadmissible in any civil or criminal case in all courts of general or limited jurisdiction in this state, except with the permission of the person whose rights have been violated in an action brought for damages under the provisions of RCW 9.73.030 through 9.73.080 which is to say, "unless the person(s) who did not give permission to be recorded now give permission for the evidence to be admitted". Since "you" would be the one making a false statement, "you" would have an interest in suppressing the video, thus "you" could withhold permission for the video to be introduced.
Recording other people without consent is a crime (§ 201 StGB). But so is threatening other people with violence (§ 241 StGB). Secret recordings and other acts can still be legitimate if they are necessary and appropriate to deflect harm (§ 34 StGB), similar to how hurting someone can be legitimate if you're acting in self-defense. If you're prosecuted for this, it will be up to the court to determine if your act was necessary and proportionate. But regardless of what you did, your recording can be used as evidence against the ex-roommate. German criminal law does not generally exclude illegally acquired evidence. The main risk of disclosing this recording is that you are also providing evidence against yourself for possible wiretapping charges (which may or may not be punishable as discussed above).
united-states In the US, the default rule is that your home is your castle. In general, nobody, not even the police, can enter your home without your permission. The main exception to this rule is that police do not need your permission if they have a search warrant to search your home. To get a warrant, the police must convince a magistrate that they have good reason (ie, &quot;probable cause&quot;), such as a gps track, to believe they will find evidence of a crime if they search the house. The police in your hypothetical are in a similar situation to police who are tracking the gps signal from a &quot;bait car/bike/phone/tablet/package.&quot; (A bait car is a car/etc that has been fitted with a camera and gps tracker, and left out as bait for thieves.) As long as the car is in public view, the police do not need a warrant to search it and arrest the person driving it. However, once the bait car is out of public view, where the police can no longer see it, they need a warrant to go in and recover it, even if they can see it on the tracker. (See, for example, the instructions for bait car programs from the Eugene and Reno Police Departments.) (For phones, which may not be in &quot;plain view&quot; even if the thief is, the police use ring programs to make the phone ring. Hearing a phone respond to a ring program gives them probable cause under the &quot;hearing&quot; version of the &quot;plain view&quot; doctrine.) Bottom line: In the US, the police need a search warrant. Since search warrants take time and effort, police may be unwilling to get a warrant for something as low valued as a phone. If the police can't or won't help, there are various options for privately enforcing one's rights. These range from the legal -- knocking on the door and confronting the thief -- to the illegal -- left to your imagination.
It's really the other way around: film crews can legally travel with the police. This is very similar or identical to what you saw on YouTube. From http://blogs.findlaw.com/celebrity_justice/2014/04/cops-and-suspects-rights-whatcha-gonna-do-when-they-record-you.html (dated 4/18/2014) "Cops" will soon begin a 10-week filming stretch in San Jose, California, for the first time in the show's 26-year history, reports the San Jose Mercury News. The "Cops" crew will hit the streets alongside San Jose's finest to provide a window into what these men and women do in America's 10th largest city. More from that link: When the officers on "Cops" arrest most of their suspects, the circumstances leading up to the arrest are out in public. However, in order to avoid unlawfully appropriating the images of those caught on "Cops'" cameras, the crew asks the arrestees to sign a release form. The "news crew" are producers who have permission from the police to follow along. As above, they ask each suspect to sign a release after the arrest. These arrests take place in public, on public streets and right-aways, where filming of the public is legal. If the arrestee does not sign the release, their face is blurred in the resulting footage that is made public. This does not mean the producers or videographers are automatically allowed into a private residence. They need a release to go onto private property (unlike the police involved in an investigation) and as such, the resident can actually forbid the cameramen from entering the house even while the police have entered. The footage from the body cams of the police are a different story; they are public employees of the local government and are bound by the laws of the locality. A search of Google News shows that in San Fransisco, the issues of the use of body cams by police and public access to that video is an ongoing issue; some laws have been finalized, others are bound to change. Around the US, some localities at this point in time allow public access to the footage from police cams; others only after department or local governmental review; still others only on in as need basis for prosecutions. ...the cop is the only one in this situation who can command the filmers to stop. Even if the "news crew" is not a news crew and just someone from the general public, it is generally legal for the public to film the police, as long as they are not causing issues with the police and stay out of the way (re: all of the recent news regarding police shootings and the footage available on YouTube and in news sources). There is case law pertaining to that, but IANAL, so I'll let someone else outline that. But https://photographyisnotacrime.com/ is a good resource. In the US, you pretty much have no expectation of privacy while in public.
