Can the FBI Reuse Evidence for Different Investigations?

Question from Sam, Can the FBI Reuse Evidence for Different Investigations?

Answer from AI:

When the FBI conducts an investigation, it often collects a wide range of evidence, including emails, which can be crucial in building a case. The scenario you’ve described raises questions about the reuse of evidence collected for one investigation in another and the implications for Freedom of Information Act (FOIA) requests. Understanding the legal framework and the rights of individuals involved is essential.

Reusing Evidence in Different Investigations

The legality of reusing evidence, such as emails collected during an investigation, for a separate investigation depends on several factors, including the scope of the original search warrant or subpoena and the relevance of the evidence to the new investigation. Generally, if the evidence was lawfully obtained during the first investigation, it can be used in subsequent investigations if it is relevant. However, specific circumstances might require the FBI to obtain a new warrant or subpoena.

FOIA Requests and Investigative Records

The Freedom of Information Act (FOIA) allows individuals to request access to records from any federal agency, including the FBI. However, there are exemptions to this rule, especially concerning ongoing investigations and national security.

  • Exemption 7(A) of FOIA allows agencies to withhold records or information compiled for law enforcement purposes that could reasonably be expected to interfere with enforcement proceedings.
  • If the FBI believes that releasing information about the bombing investigation or the subsequent bank robbery investigation could compromise their efforts, they might invoke this exemption.

Will the FBI Acknowledge the Existence of Records?

When responding to a FOIA request, the FBI may acknowledge that records exist but are exempt from disclosure under FOIA exemptions. In some cases, the agency might neither confirm nor deny the existence of records if doing so could compromise an ongoing investigation, a response known as a “Glomar” response.

Steps to Take

If you’re involved in a situation where your records are part of an FBI investigation, and you’ve made a FOIA request, here are some steps you might consider:

  1. Review the FBI’s response to your FOIA request carefully to understand which exemptions they are citing.
  2. Consider filing an appeal if you believe the FBI has improperly withheld records. The FBI’s response should include information on how to do this.
  3. Consult with a legal professional who can provide personalized advice based on the specifics of your case. They can help you understand your rights and the best course of action.


The reuse of evidence collected in one investigation for another is a complex issue that depends on the specifics of each case. While the FBI can use evidence across different investigations if it was lawfully obtained, there are strict rules governing what information can be shared with the public, especially through FOIA requests. If you find yourself in a situation where you’re seeking records from the FBI, it’s crucial to understand your rights and the legal landscape. Consulting with a legal professional can provide you with guidance tailored to your situation.

Note: Legal procedures and rights can vary widely, and it’s important to consult with a legal professional for personalized advice.
