ParallelConstruction.org is a public education resource dedicated to exposing how law enforcement agencies launder illegally-obtained evidence into criminal prosecutions—and what you can do about it.
Our Mission
To make the practice of parallel construction so widely understood that it can no longer operate in the shadows.
The Problem
The Fourth Amendment is supposed to protect Americans from unreasonable searches and seizures. Evidence obtained unconstitutionally should be inadmissible in court. But parallel construction allows law enforcement to have it both ways: conduct illegal surveillance, then hide its origins by "reconstructing" the investigation through legitimate-looking means.
Most defendants never learn how they were really found. Their attorneys can't challenge evidence they don't know exists. Judges and juries make decisions based on incomplete information. The constitutional protections that should apply become meaningless.
What We Do
This site provides:
• Clear explanations of what parallel construction is and how it works
• Documentation of cases and exposés that have revealed the practice
• Practical guidance for defendants and defense attorneys
• Resources for journalists, researchers, and advocates
• Connections to organizations fighting for Fourth Amendment rights
Who We Are
This site is maintained by civil rights advocates who believe that constitutional protections only matter if they're actually enforced. We are not attorneys and do not provide legal advice—but we believe everyone deserves to understand how the system actually works.
We welcome contributions, corrections, and case tips. If you have information about parallel construction practices, contact us.
