Can the police examine the digital contents of your smartphone beyond the IMEI if you are searched or arrested? If you are arrested, can your messages be read and your contacts be retrieved by demand of the police? If so, under what circumstances and caveats?
Yes. The police have the power to seize your phone as evidence under the Police and Criminal Evidence Act 1984, the Misuse of Drugs Act 1971, and the Terrorism Act 2000. There are no caveats or defined circumstances other than having a reasonable belief that the data on the phone forms evidence against you. They do not require a warrant to access your phone, and many police forces in the UK are using commercially available software to bypass password/PIN protection on your phone 1. In the event you do not provide your password/thumbprint/facial scan/PIN to officers to unlock your phone, you can be served with a Section 49 Notice under the Regulation of Investigatory Powers Act 2000 (RIPA) which compels you to provide that information. Failure to do so can lead to a conviction under Section 53 RIPA, in addition to any other offences you may be charged with.
Yes. At international borders and international airports (because those are the equivalent of a border), US customs officers may do searches of people and belongings without a warrant and without any particular reason to think they'll find contraband. This includes the authority to do some level of disassembly of the car, if they then reassemble it. See United States v. Flores-Montano, 541 U.S. 149. This is known as the "border search exception." Moreover, police normally don't need warrants to search your car if it was mobile when they found it and if they have probable cause to believe they'll find contraband. This is known as the "automobile exception" or the "motor vehicle exception." It was established in Carroll v. US, 267 U.S. 132. Individual states may have stricter requirements on police searches, but the Fourth Amendment doesn't require police to get a warrant to search your car if, say, you drove it up to a checkpoint and they have probable cause. The difference at a border is that they don't need probable cause and the car never had to be mobile: they can search you on a hunch.
What a statute means can be difficult to determine. There are several approaches to statutory interpretation that could be helpful: Textual: The plain meaning doesn't confine "use" to a few particular types of uses. The plain text provides an expansive prohibition on any use of an electronic communication device. Legislative history/legislative intent: The previous version of the subsection did limit prohibited uses to only composing, sending, or reading electronic messages. Given the amendment, it seems that the legislature no longer desired that limitation. When the bill was introduced, Rep. D'Amico stated the purpose of the bill was to "[expand] the prohibition on driving while using an electronic communication device to include uses beyond composing, sending, or reading an electronic message." During debate, when asked what a person should do that doesn't have Bluetooth, Rep. D'Amico suggested "You put it on speaker phone". When asked, "Where would you place the phone?", Rep D'Amico replied, "Wherever you feel like; just not next to your ear." During the same debate, D'Amico described the bill: "What House Bill 1247 does is ban handheld cell phones while driving a vehicle." In my opinion, the declaration of the bill's sponsor, and the debate surrounding the bill treated it as expanding the prohibition from including only texting and email to also include voice conversations. As far as I can tell, the full scope of "using" under this statute hasn't been tested in court, but I could see this going either way. The plain text provides an expansive prohibition on any use of an electronic communication device. However, a court might also be convinced by the legislative intent that only aims to add handheld voice communications to the previous list of prohibited activities (or it least it could be argued that this is the case). Further, under a purposive construction, a court could even look beyond the explicit legislative intent and find that the core purpose was to prevent distraction, in which case "using" could include any activity on your electronic device that distracts you as if you were texting, or making a phone call (eg. selecting the next song to play in your music app).
Is mere accusation without evidence other than testimony of the accuser, grounds for arrest in the UK? It depends on the circumstances, especially when dealing with non-recent allegations where independent and corroborative evidence may be difficult to locate and/or recover, but in my experience it is very rarely an option to arrest soley on the say-so of one complainant unless there is a compelling reason to do so. It's also fraught with potential risks - Operation Midland being a prime example of when it can go horribly wrong. Also, no-one can &quot;call the police and have someone arrested&quot; in the united-kingdom - the police are under a duty to carry out a &quot;proportionate investigation&quot; in to allegations of crime and then make their own minds up on how to proceed based on the available intelligence and evidence. Focussing on england-and-wales, the most commonly used power of arrest* is at s.24 of the Police and Criminal Evidence Act 1984 which, along with PACE Code G, requires an officer to: Reasonably suspect that an offence is being, has been or will be committed. On a scale of 0 to 10 - with 10 being total knowledge and 0 being no opinion at all - suspicion may be as low as 2 or 3 whereas belief starts at 7 or 8. And reasonably believe an arrest is necessary. One commonly used mnemonic for the Necessity Test under s.24 is: ID COP PLAN: Investigation - prompt and effective investigation of offence or conduct Disappearance - prevent prosecution being hindered by disappearance of a person Child / Vulnerable person - protection of Obstruction of highway Physical injury to themselves or someone else Public (in)decency Loss or damage to property Address not know Name not known I cannot say why the officer did not make an arrest in the OP's case. I surmise that he did not deem it necessary based on the above mandatory criteria but rather considered that a voluntary attendance interview would be the most appropriate course of action given the circumstances and information available to him at the time. *There are other statutory and common-law powers of arrest, but they all follow the same procedures as above
The law 'doesn't care' how the call is recorded. What matters is whether or not you should inform / should have informed the participant(s) in the circumstances. In circumstances where you are acting as an ordinary member of the public, in the course of a purely personal or household activity, not in a journalistic capacity, regulated business or other circumstances where the rules may differ: In the UK it is not unlawful for a private person to record a phone call without the permission or foreknowledge of the other participant(s) - provided the recording is for 'personal use'. If you intend to share the content of the call with a third-party or make it public, then you must inform the person ahead of recording it. If you try to use a covertly recorded call as evidence in court, the court may or may not exclude it depending on the circumstances.
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.
That the cop claims to be your friend is not more illegal than a salesman claiming that he has "the best offer" for you because he likes you (in fact didn't you see any film about the good cop/bad cop routine?) The term you are looking for is Entrapment. The (very simplified) basic idea is that police officers can promote the comission of a crime to catch criminals but cannot "trap" innocent people into it; the difference being that their persuassion should not turn otherwise innocent people into criminals. An extreme example would be if the cop threatens the target into commiting a crime. For the more usual situation when a cop promotes a crime to catch the criminal, I saw it explained (just for illustration purposes, it is not that you are safe when the cop insists a third time) as it follows: Legal: Cop) Oh boy! The place where I work is full of cash and they don't even have alarms or store it in a safe box. If someone helps me, we could go this night and take all of it. Are you interested? Target) I don't know. Cop) Trust me, it will be easy, nobody is there at night and it will be just a couple of hours. Target) Ok, count me in. Illegal Cop) Oh boy! The place where I work is full of cash and they don't even have alarms or store it in a safe box. If someone helps me, we could go this night and take all of it. Are you interested? Target) I am not a thief. Cop) Come on, it will be easy, the place is insured and nobody will be hurt. Target) Not interested. Cop) We can get 5000 US$ each one, just for a night of work. Didn't you told me that you had troubles with your bank? You could solve those overnight! Target) Maybe you are right, but I have no experience with these things... Cop) Do not worry, I will tell you what you need to do. Target) Ok, count me in. Note that it is not only "the cop insisted a lot". For the drug dealer example, if the cop insisted a lot but, when agreed, the boy produced the drug from his pocket, already packaged for sale, it would not be entrapment. OTOH, if the guy had told "I do not know where to buy drugs" and the cop had told him "go talk with X so he sells you the drug", then it could be considered entrampment. In any case, this is generic information only, entrapment is difficult to prove and will depend on the views of the judge/jury so, no matter how enticing that criminal offer is, just don't do it.
It can go either way. If detectives have been working to build a big conspiracy case against you, they might get charges filed before they roll up to arrest you. If a cop catches you mugging someone, they'll arrest you on the spot and charge you later.
