Law enforcement agencies can request or demand that tech companies hand over data such as location and subscriber information. In the US, the Fourth Amendment speaks of a person’s right to be secure against unreasonable searches or seizures, which forms the basis for privacy law development in the country. In 2018, a federal judge ruled that people with smart meters have a reasonable expectation of privacy, and law enforcement would require a warrant to access that data. However, there are concerns about the use of administrative subpoenas, which do not require a judge's signature, and the ability of law enforcement to access data directly from tech companies through various forms of legal requests.

What You'll Learn
Law enforcement accessing physical devices
Law enforcement agencies can request or demand that tech companies hand over data such as location and subscriber information. This can be done by accessing physical devices or through legal requests.
Accessing Physical Devices
Law enforcement agencies can subpoena a device or obtain a search warrant to go through a person's phone. If a phone is locked or encrypted, police can use mobile device forensic tools (MDFTs) to break the encryption or bypass the lock screen if they have a warrant. MDFTs can copy all the data from a cellphone and sort it, making it easier for law enforcement to search through. These tools can also compare facial images from police databases to photos stored on the phone and classify text conversations by topic.
To navigate mobile device searches, law enforcement must follow certain legal processes and best practices. Search warrants must specify the device to be searched, which in the case of a mobile device, is the device itself. For mobile phone records, the location is the physical address of the mobile phone provider. It is beneficial to include a detailed physical description of the device, including any damage, serial number, and IMEI number.
The widespread use of mobile devices has proven fruitful for law enforcement. Through proper legal channels, they can access communication, photographs, web searches, location history, and deleted content. However, improperly navigating this process could result in losing mobile phone evidence due to the "fruit of the poisonous tree" doctrine, which states that evidence obtained from an illegal search is inadmissible in court.
Legal Requests
Law enforcement agencies can also obtain user data directly from tech companies through various forms of legal requests, such as administrative subpoenas, emergency legal requests, and court orders. Google, for example, received over 39,000 requests for user information in the last six months of 2020 and complied with over 80% of them. In some cases, companies may voluntarily provide data without a court order.
While these requests may be necessary for law enforcement, they have raised privacy concerns. Privacy policies in apps often include clauses stating that user data will be shared in response to law enforcement requests. Additionally, many requests come with gag orders, preventing companies from notifying users that their information has been requested for extended periods.

Administrative subpoenas
The Inspector General Act of 1978 authorises "each Inspector General" to "require by subpoena the production of all information, documents, reports, answers, records, accounts, papers, and other data and documentary evidence necessary in the performance of the functions assigned by [the Act]." Federal courts have upheld this authority even in situations where the Inspector General is cooperating with criminal investigations by the Justice Department.
The Department of Justice, Department of the Treasury, and the Cybersecurity and Infrastructure Security Agency (CISA) are among the agencies that have the authority to issue administrative subpoenas. CISA, for example, can issue administrative subpoenas to identify and notify entities with vulnerable digital systems that are connected to critical infrastructure.
While administrative subpoenas can be a useful tool for law enforcement, they have also raised concerns among privacy advocates. Some experts worry that agencies like Immigration and Customs Enforcement (ICE) may be using administrative subpoenas to expand their surveillance of US citizens. In response to these concerns, lawmakers have called for reforms to ensure that administrative subpoenas are used consistently and fairly while still allowing legitimate emergency requests.

Smart meters
The Fourth Amendment, which establishes the constitutional parameters for government investigations, may restrict law enforcement access to smart meter data or establish rules for its acquisition. The applicability of the Fourth Amendment depends on the purpose of data collection. If the data is collected by a publicly owned utility for ordinary business purposes, such as billing or informing the customer of their usage patterns, it does not violate the Fourth Amendment. However, if the same data is collected at the request of law enforcement to aid in criminal investigations or for other administrative purposes, the Fourth Amendment protections may apply.
The determination of whether smart meter data is protected by the Fourth Amendment involves assessing whether the government invaded a reasonable expectation of privacy. While some states consider utility records as public records accessible for public inspection, others have provided statutory and constitutional protections for these records. Additionally, a significant body of cases has refused to recognize constitutionally protected privacy interests in information provided by customers to businesses as part of their commercial relationships, which is known as the third-party doctrine.
Law enforcement may also be able to access smart meter data under specific statutes, such as the SCA, ECPA, and the Foreign Intelligence Surveillance Act (FISA). Furthermore, companies might voluntarily disclose user data to law enforcement agencies without the need for a court-ordered subpoena.
Overall, the discussion surrounding smart meter data and law enforcement access highlights the delicate balance between effective crime investigation and the protection of consumer privacy within their homes.

Emergency legal requests
Google also discloses user data in emergency situations, particularly when a person may be in serious physical danger. Google may be asked to set aside a copy of specific information while a government agency applies for legal process to compel the disclosure of that information. However, Google requires a valid legal process before producing information in response to a request from a government agency, even in an emergency. Google has a track record of pushing back against inappropriate government demands for user data.
Tech companies like Google often comply with administrative subpoenas, which do not require a judge's signature but are also not self-enforcing. Law enforcement agencies can take companies to court if they refuse to comply with these requests.
Emergency data requests have been spoofed by hackers to obtain confidential information. Implementing digital signatures has been proposed as a security measure, but this would require substantial technical and legal effort. There is also no master list of authorised law enforcement personnel, making it difficult for service providers to verify the legitimacy of the requests.

Tech companies sharing consumer data
Tech companies collect and share consumer data in a variety of ways. Privacy policies often contain legal jargon that makes it difficult for consumers to understand what data is being collected, how it is protected, and how it is shared. Tech companies like Google, Facebook, Twitter, Amazon, and Apple collect and share data for various purposes, such as improving their services, preventing fraud, and marketing. For example, Amazon shares data with third-party service providers and co-branded companies, while Apple does not share data with third parties for marketing purposes but does share data with customer service and delivery personnel.
Law enforcement agencies can access consumer data from tech companies through legal requests, such as subpoenas and search warrants. They can also obtain data by accessing physical devices, using mobile device forensic tools, and through emergency legal requests. In the United States, agencies like the police, Immigration and Customs Enforcement (ICE), and the FBI can request and obtain user data directly from tech companies. Google, for instance, received over 39,000 requests for user information in the last six months of 2020 and complied with over 80% of them.
The Federal Trade Commission (FTC) has expressed concern over the collection and sale of consumer data by tech companies without adequate protections, especially regarding children and teens. The FTC has recommended limiting data collection, developing enforceable policies, minimizing data retention, and providing more control to users to protect their privacy and prevent potential harms such as identity theft and stalking.
Tech companies have access to a wealth of consumer data, including browsing history, purchase behaviour, and personal information. This data is used to improve products, personalize content, and target advertising. While data collection can provide benefits to consumers, such as improved services and content, it is important for individuals to be aware of the data being collected and shared, as well as their rights under privacy laws such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).

Frequently asked questions
Law enforcement can demand energy data in mass, but they need a warrant to do so.
Law enforcement can obtain energy data by requesting it from tech companies through various forms of legal requests, such as subpoenas or search warrants. They can also access energy data through smart meters, which record energy usage data centrally and can provide insights into residents' daily lives and routines.
The Fourth Amendment of the US Constitution protects against unreasonable searches and seizures, which may include the collection of energy data by law enforcement. The amendment applies when the government invades an area where a person has a reasonable expectation of privacy. In the case of smart meters, a court would consider the purpose of the data collection, distinguishing between ordinary business purposes and criminal investigations.
