Law enforcement agencies have several methods to access an individual's purchase history. Police can obtain a warrant or subpoena to compel search engines, websites, or internet service providers to hand over search history. This requires probable cause and judicial approval. Search engines like Google collect data about search queries, browsing habits, and websites visited. This data is stored in vast databases and is easy to retrieve. Internet service providers (ISPs) also collect data on online behaviour, including purchase history, and can see which websites are visited and how long is spent on each. This information can be requested by law enforcement, often through legal processes. If an individual is suspected of a crime, their browsing data can be subpoenaed by the prosecution.

Law enforcement can access basic subscriber information without a warrant
In most cases, law enforcement agencies must obtain a warrant or court order to access an individual's internet browsing data. This is supported by the Electronic Communications Privacy Act (ECPA), which upholds the Fourth Amendment of the US Constitution, protecting citizens from unreasonable searches and seizures. However, there are exceptions and loopholes that allow law enforcement to access certain types of information without a warrant.
Basic subscriber information, such as name, address, phone number, and payment history, can generally be accessed by law enforcement without a warrant. This information is held by internet service providers (ISPs), and while a warrant is typically required for more detailed browsing data, basic subscriber information can often be obtained without one. This is true in both the US and Canada, where the Strong Borders Act and Bill C-2, respectively, grant law enforcement the right to demand basic subscriber information without a warrant.
In Canada, the Supreme Court has weighed in on this issue, highlighting the expectation of privacy that internet users have regarding their personal information. The court acknowledged that while police have lawful powers to search without a warrant in exigent circumstances, a simple request for subscriber information constitutes a search that requires a court-authorized warrant. Despite this, in a case involving child pornography, the court allowed the evidence obtained without a warrant—the subscriber's name and address linked to their IP address—to stand, as the police were acting under what they reasonably believed to be lawful authority.
While law enforcement agencies typically require a warrant to access browsing data, there are exceptions and legal mechanisms that allow them to obtain basic subscriber information without one. This balance between privacy rights and law enforcement needs varies across different jurisdictions, and it is important for individuals to understand their rights and the limits of law enforcement powers in their respective countries.

Search history can be used to establish a motive or knowledge of a crime
Search histories can be accessed by law enforcement agencies and used as evidence to establish a suspect's motive, intent, or premeditation in a crime. This can be done by subpoenaing browser data, which requires demonstrating that the information is relevant to the case and cannot be obtained by other means.
In the United States, the Fourth Amendment protects citizens from unreasonable searches and seizures, and law enforcement officials must obtain a warrant based on probable cause before accessing private information such as search histories. The Electronic Communications Privacy Act (ECPA) upholds this amendment and applies to computer-stored data like emails and search histories. However, under the Patriot Act, the FBI can access search histories without a warrant.
Search histories can reveal a lot about a person's interests, intentions, and knowledge over time. For example, a defendant's browser history with search terms like “how to dispose of a body” or "how to sell heroin" may indicate premeditation and planning. Similarly, in murder and sex crime cases, suspects may have searched for the victim's personal information or researched methods of committing the crime. In cases of harassment, browser data can reveal the use of anonymous accounts, and in stalking cases, it can show a history of searching the victim's name or tracking their location.
While incognito mode and deleting browser history may give a false sense of privacy, internet service providers (ISPs) do keep records of user search histories, which can be accessed by law enforcement with proper legal authorisation.

Police can seize devices to access search history directly
If the police have access to your device, they can see a variety of information, including the specific search terms you used, the websites you visited, the amount of time spent on different sites, and even your location data. This information can be used to build a case against you, as it can provide insight into your state of mind, behaviour, and intent. For example, searches for "how to dispose of a body" or "how to make a bomb" could be used as evidence of intent or premeditation.
In addition to seizing devices, police can also request information from internet service providers (ISPs). They can track down internet protocol (IP) addresses and inspect the search history associated with that IP address. This allows them to find the names and contact information of potential suspects or investigate the search histories of known suspects for links to a crime.
It's important to note that there are legal protections in place to safeguard your privacy. The Electronic Communications Privacy Act (ECPA) and the Fourth Amendment of the Constitution protect individuals from unreasonable searches and seizures. To access computer-stored data like emails and search histories, law enforcement officials typically need a warrant based on probable cause.
While online privacy is a concern, understanding your rights and the limits of law enforcement's power is crucial. If you have been charged with a crime and your search history is being used as evidence, skilled defense attorneys can assess and challenge the legality and relevance of the evidence presented.

The Fourth Amendment protects citizens against unreasonable searches
The Fourth Amendment of the US Constitution protects citizens against unreasonable searches and seizures. This means that law enforcement officials must have warrants issued based on probable cause to infringe on a person's privacy and security to discover evidence. The Fourth Amendment reflects the Framers' intent to avoid the unjust searches and seizures they experienced under English rule.
The Electronic Communications Privacy Act (ECPA) was enacted to uphold the Fourth Amendment, which has evolved to include computer-stored data like emails and search histories. When investigators ask ISPs for information, the ECPA, specifically the Stored Communications Act (SCA), prevents ISPs from voluntarily providing specific customer communication information and records without being presented with a search warrant based on probable cause.
In general, the Fourth Amendment means that police cannot search a person without a warrant or probable cause. However, the Supreme Court has grappled with what is considered "reasonable" for over two hundred years, and several exceptions to the warrant requirement have been made. For example, school officials need not obtain a warrant before searching a student under their authority; rather, a search of a student need only be reasonable under the circumstances. Similarly, an officer may conduct a pat-down of the driver and passengers during a lawful traffic stop, and they need not believe that any occupant of the vehicle is involved in criminal activity.
In the digital age, it is important to note that your internet history is never truly private. Law enforcement can access basic subscriber information from an internet service provider (ISP) without a warrant or court order. This includes name, address, phone number, and payment history. They can also request records showing when an account was created or canceled and IP addresses used. If you have been charged with a crime, your browser data, including your search history, can be subpoenaed by the prosecution. This data can be used to establish a motive for a crime or that you had the knowledge to commit it.

Search history can be used against you in court
Your search history can be used against you in court, but there are certain limitations. In the US, the Fourth Amendment protects citizens from unreasonable searches and seizures. This is upheld by the Electronic Communications Privacy Act (ECPA), which includes computer-stored data like emails and search histories.
Law enforcement must obtain a warrant or court order to access your search history, and they need probable cause to do so. However, there are some exceptions, such as when basic subscriber information is requested, which can include name, address, phone number, and payment history.
If you have been charged with a crime, your browser data, including your search history, can be subpoenaed by the prosecution. This can be used to establish intent, motive, or communication with co-conspirators. For example, in murder cases, suspects may have searched for products like guns or poisons, or researched methods of committing the crime. In sex crime cases, suspects may have tried to find personal information about the victim.
In white-collar crime cases, the prosecution may look into your browser history to see if you attempted to break into a security system. If you are suspected of drug possession, investigators may look into whether you searched for local drug dealers online. Certain searches can also raise red flags, such as searching for child pornography, which could be a violation of the Child Online Protection Act (COPA).
It's important to note that your search results alone cannot be the sole basis for a conviction, and the prosecution must prove that you intended to or did commit a crime with the aid of your search results. Additionally, your attorney can argue against the admission of your search history as evidence, claiming that it is irrelevant, taken out of context, or obtained illegally.
