Can Text Messages and Social Media Be Used as Evidence in a Federal Case?

At Deandra Grant Law, Attorney James Lee Bright has more than 25 years of federal experience handling cases involving complex digital evidence which means evaluating how digital evidence was obtained, whether it was properly preserved, and whether the government’s interpretation of that evidence is accurate.

How the Government Gets Your Digital Communications

Search Warrants for Devices

When federal agents execute a search warrant at your home or during an arrest, they seize electronic devices such as phones, computers, tablets, external drives. These devices are then subjected to forensic examination using tools like Cellebrite, GrayKey, and EnCase that can extract text messages, deleted messages, app data, call logs, photos, videos, browsing history, location data, and metadata. Modern forensic tools can often recover data that the user believed was permanently deleted.

Legal Process to Service Providers

The government uses multiple legal mechanisms to obtain data directly from technology companies and service providers:

• Search warrants (required for content). Under the Stored Communications Act (18 U.S.C. §2703) and the Supreme Court’s decision in Carpenter v. United States (2018), the government generally needs a warrant supported by probable cause to obtain the content of stored communications including emails, text messages stored on a provider’s servers, direct messages, and cloud-stored files.
• Court orders (§2703(d) orders). For non-content records, such as subscriber information, IP addresses, login times, and connection logs, the government can obtain a court order based on “specific and articulable facts” showing relevance to an investigation. This is a lower standard than probable cause.
• For basic subscriber information (name, address, billing records), the government can issue an administrative subpoena without judicial approval.
• National Security Letters (NSLs). In national security investigations, the FBI can issue NSLs for certain categories of records without judicial involvement.

Preservation Requests

Before obtaining a warrant or court order, the government can send a preservation request to a service provider under 18 U.S.C. §2703(f), requiring the provider to preserve a user’s data for 90 days (renewable). This prevents data from being automatically deleted while the government prepares its legal process. You will not be notified of a preservation request.

What the Government Does with Digital Evidence

In federal cases, digital evidence is used in multiple ways:

• Direct evidence of criminal conduct. Text messages discussing drug transactions, photos of contraband, or social media posts displaying firearms are used as direct evidence of the charged offense.
• Evidence of conspiracy and association. Communication patterns, group chats, and contact lists are used to establish relationships between co-conspirators and the organizational structure of alleged criminal enterprises.
• Timeline and location evidence. GPS data, cell site location information (CSLI), and metadata timestamps are used to place the defendant at specific locations at specific times.
• Prior statements in text messages or social media posts can be used to contradict a defendant’s testimony or other evidence presented at trial.
• Sentencing evidence. Even evidence that is inadmissible at trial may be considered at sentencing under the more relaxed evidentiary standards that apply in federal sentencing proceedings.

How We Challenge Digital Evidence

Our ACS-CHAL forensic credentials and Lee’s federal trial experience combine to challenge digital evidence at every stage:

• Fourth Amendment challenges. Was the search warrant for the device or provider data supported by probable cause? Was the warrant sufficiently particular? Did agents exceed the scope of the warrant during the forensic examination? Lee files motions to suppress unlawfully obtained digital evidence.
• Authentication challenges. The government must prove that the digital evidence is what it claims to be. Who actually sent a text message? Was the social media account controlled by the defendant? Could someone else have had access to the device? Were messages altered, fabricated, or taken out of context?
• Forensic methodology challenges. Was the device properly imaged with write-blocking? Was chain of custody maintained? Were forensic tools properly calibrated and validated? Were extraction reports accurately interpreted? Our forensic team evaluates the government’s digital forensic work at a technical level.
• Metadata and timestamp challenges. Digital timestamps can be affected by time zone settings, device clock errors, and platform-specific behaviors. We examine whether the government’s timeline narrative is actually supported by the metadata.
• Completeness challenges. The government may present selected messages out of context while omitting surrounding communications that change the meaning. Lee demands complete production and presents the full context to the jury.
