Powers of Entry when it is summary-only offence I was watching this YouTube video by Crimebodge. At 10:10 he explains that the police only have powers of entry to arrest somebody for indictable offences (like rape), and not for summary offences (like harassment). I understand there are other scenarios when they can enter, for example if they are pursuing someone that just ran into a house. Question #1: If someone makes a complaint to the police about an indictable offence, such as rape, and another person makes a complaint to the police about a summary offence, such as harassment, would the police then need a warrant to enter the house and arrest the person? Question #2: What would happen if it was an either way offence (one that could be tried in a Magistrates' Court or the Crown Court) - would it perhaps depends upon the seriousness as to whether police could use their powers of entry? Question #3: If it is an indictable offence, is it enough for an alleged victim to go to a police station and put in a complaint so the police can enter your house without a warrant to arrest you, or must the police officer have seen it happen otherwise it requires a warrant? These questions are just for England and Wales.
If the conditions at s.17 and s.24 PACE 1984, and PACE Code G are satisfied for the offence of rape then there is no requirement for a warrant. Once the suspect is in police custody he may be further arrested for suspected harrassment if any of the necessity criteria are met - this will depend on the particular circumstances of the case. An either way offence is, for these purposes, regarded as an indictable offence. A constable does not need to physically see an offence being committed, but he must have (a) reasonable grounds to suspect an offence has been committed (b) reasonable grounds to believe an arrest is necessary (c) the requesit belief to satisfy s.17 PACE 1984. All this will come from conducting a proportionate investigation in to the allegations.
Edit: I didn't notice a that this question was tagged for Canada; this answer is based on U.S. law. "Must you stop walking" and "can the police detain you for leaving" are different questions. Must you stop? I'd expect a lot of variation from state to state, but there are definitely situations in which you must stop. In Ohio, for instance, an officer who "reasonably suspects" that that you have committed, are committing, will commit, or have witnessed the commission of violent felony, is permitted to stop you and ask for your name, address and date of birth, and it is a crime to refuse to provide that information. R.C. 2921.29. But at the moment the officer asks you to stop, you're in a tricky position. If you haven't done anything wrong, you'd be inclined to think that the officer has no basis to stop you and that you're justified in walking away. But if someone just called the police and said someone fitting your description just robbed a store two blocks away, the officer has reasonable suspicion that you committed a violent felony, but you have no way of knowing that. This sort of thing happens pretty much all the time. In the absence of that reasonable suspicion, though, Ohio courts have repeatedly held that it is not obstruction for you to just walk away (or even run!) from the officer. Can the police detain you for walking away? Obviously, if you're in a situation where it is a crime to not answer questions, the police can detain you because they just watched you break the law. But what about when you're within your rights not to answer? The police can still detain you with a Terry stop when they have a reasonable and articulable suspicion that you are committing a crime, or that you just did, or that you're about to. And they can continue that Terry stop until that suspicion is confirmed or dispelled, or until they can't reasonably expect to get anymore information by detaining you. Based on the facts you described, it seems unlikely that they could legally detain you based on your termination of the conversation. Still, I imagine that there could be circumstances where they might stop someone, ask questions, and then reasonably suspect that the person was engaged in a crime based on his decision to walk away, especially if the person hasn't explicitly invoked his Fifth Amendment right to silence.
I'm not sure a case of harassment could be made out (it would depend on the circumstances in which you purportedly did those things or threatened her, except for touching her. Sexual assault The Sexual Offences Act 2003 defines sexual assault as: (1) A person (A) commits an offence if— (a) he intentionally touches another person (B), (b) the touching is sexual, (c) B does not consent to the touching, and (d) A does not reasonably believe that B consents. (2) Whether a belief is reasonable is to be determined having regard to all the circumstances, including any steps A has taken to ascertain whether B consents. To your questions: What is the law on a 16 year-old doing the things listed above with a 14 year-old? Same as the above, except what would happen if it was made out that there was not consent? For sexual assault, it is presumed that if the person is between the ages of 13 and 16, they do not have the capacity to consent. That is - if there is no proof of consent, you are guilty of the offence, if the requisite mens rea - intent - to touch them can be proved. For everything else - it might amount to harassment but that is probably a stretch, I don't see the elements being made out. However, there are certain limits to what people can consent to - you can't consent to someone murdering you in most jurisdictions, for example. ... what would be the best way to go about disproving (in a court scenario) that I did all of these things? You do not have to disprove that you did these acts - it is the job of the prosecution to adduce evidence beyond reasonable doubt that you have done so. You can present evidence that satisfies an evidentiary burden that you did not do these acts, such as not being able to do so (by being in another place), or not intending to do the act. However, you would need to prove that you had consent and believed she was 16 or over to stand a reasonable chance of escaping conviction for the above crime, if prosecuted. As Martin has said - you need to get a lawyer for the right answer here.
Section 4A of the Public Order Act 1986 (which was amended by section 154 of the Criminal Justice and Public Order Act 1994). [F14A Intentional harassment, alarm or distress. (1)A person is guilty of an offence if, with intent to cause a person harassment, alarm or distress, he— (a)uses threatening, abusive or insulting words or behaviour, or disorderly behaviour, or (b)displays any writing, sign or other visible representation which is threatening, abusive or insulting, thereby causing that or another person harassment, alarm or distress. (2)An offence under this section may be committed in a public or a private place, except that no offence is committed where the words or behaviour are used, or the writing, sign or other visible representation is displayed, by a person inside a dwelling and the person who is harassed, alarmed or distressed is also inside that or another dwelling. (3)It is a defence for the accused to prove— (a)that he was inside a dwelling and had no reason to believe that the words or behaviour used, or the writing, sign or other visible representation displayed, would be heard or seen by a person outside that or any other dwelling, or (b)that his conduct was reasonable. (4)F2. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . (5)A person guilty of an offence under this section is liable on summary conviction to imprisonment for a term not exceeding 6 months or a fine not exceeding level 5 on the standard scale or both.]
It is possible that there is such a booklet in some jurisdiction, and that local police are required to carry that booklet and show it to persons on demand. This link (apparently) publicly provides the police manual for the city of Seattle, except it is 5 years and a major lawsuit out of date. No provision seems to exist that requires showing authority to detain, when requested. There is no general requirement for all police and all laws, in the US, and the full set of state, county and city codes would be impractical to lug around. If required by law to carry and display some such document, then by law a person can demand to see a police officer's authority to detain. Even without such a law, you have a First Amendment right to challenge the detention, but that does not also enable you to resist arrest. A detention is not invalidated by the fact that the detainee is unsatisfied that the detention is legal.
If that which you describe in your comment ( Facebook post as only basis for warrantless search) is, and can be shown, to be the only basis for the search, and there was no evidence of a crime in plain view when they arrived.....then yes, it is likely the search and all evidence acquired from the search would be excludable. As to whether the individual could still be prosecuted, that depends if a case could be built independent of the evidence collected during the search.
There are two questions here: Is it really the police, or someone pretending to be the police in order to stage a home invasion? If it is the police they will be wearing uniforms and showing you their badges. I don't know how common it is for criminals to impersonate police officers. Do they have a valid search warrant? Once you have established that they really are police your best course is to stand back and let them in. Arguing about search warrants and &quot;fruit of the poisoned tree&quot; is a job for a lawyer later on. One option might be to quickly dial 911, put the phone down but still listening, and then open the door while saying &quot;are you police, can I see your badge?&quot;. If they are police then no problem. If they turn out to be imposters then the 911 dispatcher should be able to figure it out and send the real police around.
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.
