The Short Answer

Prosecutors have discovered that social media accounts are gold mines of potential evidence. Your Facebook posts, Instagram stories, Snapchat messages, tweets, TikTok videos, and even your Venmo transactions can be used to establish motive, intent, location, relationships, state of mind, and even admissions. In sex crime cases, social media evidence is often used to establish communication between the defendant and the accuser, to demonstrate relationship dynamics, and to corroborate or contradict testimony.

Can Social Media Posts Be Used Against You in a Texas Criminal Case?

But social media evidence is not as straightforward as prosecutors make it appear and it can be challenged on multiple grounds.

How Prosecutors Obtain Social Media EvidenceCan Social Media Posts Be Used Against You in a Texas Criminal Case?

  • Public posts. Anything you post publicly on social media can be viewed, screenshotted, and preserved by law enforcement without a warrant. If your profile is public, your posts, photos, check-ins, friend lists, and comments are all accessible.
  • Subpoenas and warrants. For private messages, account data, IP logs, and other non-public information, law enforcement must obtain legal process from the platform. Platforms like Facebook, Instagram, Snapchat, and others maintain subscriber information, login records, IP addresses, and stored communications that can be obtained through subpoenas, court orders, or search warrants.
  • Forensic collection from devices. When law enforcement seizes a phone or computer, forensic analysis can extract social media data including messages, cached content, login tokens, and app data even from apps the user thought were ephemeral.
  • Complainant or witness screenshots. Prosecutors sometimes rely on screenshots of social media conversations provided by the alleged victim or witnesses. These screenshots are among the most problematic forms of evidence.

Authentication and Reliability Challenges

Screenshots Are Not Forensic Evidence

A screenshot of a social media post or conversation is a photograph of a screen. It can be fabricated, edited, or taken out of context. Screenshots do not carry metadata, cannot be verified against the platform’s records, and do not establish that the account’s owner was the person who created the post or sent the message.

Account Ownership vs. Account Use

The fact that an account is registered to the defendant does not prove the defendant made a specific post or sent a specific message. Accounts can be hacked, shared, left logged in on other devices, or accessed by others who know the password. A forensic analysis of login records, IP addresses, and device identifiers is necessary to attribute specific activity to a specific person.

Context and Completeness

Prosecutors select the posts and messages that support their narrative and ignore the rest. A single message taken out of a months-long conversation can be made to look incriminating when the full context tells a completely different story. Doug demands complete social media records and presents the full context to the jury.

Ephemeral Content

Platforms like Snapchat are designed to delete content after viewing. When prosecutors present Snapchat evidence, the defense must examine how that content was preserved — was it forensically collected, or is it a screenshot that may have been altered?

How Doug Challenges Social Media Evidence

  • Demanding forensic collection from the platform rather than accepting screenshots
  • Examining IP logs and device identifiers to determine who actually accessed the account
  • Presenting complete conversation threads rather than the prosecution’s selected excerpts
  • Investigating whether the account was compromised, shared, or spoofed
  • Challenging the authentication of social media evidence through pretrial motions
  • Retaining independent forensic experts to analyze social media data and present their findings
