What did the FBI and Department of Justice investigate and conclude about the New Jersey men detained after 9/11?

1. What the supplied DOJ and FBI documents actually cover

The Justice Department links in the packet are press releases and local U.S. Attorney announcements about modern prosecutions in New Jersey—examples include a 2025 District of New Jersey release about a false‑report conspiracy and larger narcotics/firearms indictments—each crediting FBI and local partners for investigations ^{[1] [4] [5]}. The FBI links in the set are field‑office press pages and a historical 9/11 case summary that recounts the attacks and the broader FBI response, not post‑9/11 detention adjudications of specific New Jersey men ^{[6] [7] [8] [3]}.

2. Direct answer to the user’s question: what the FBI/DOJ investigated and concluded

Available sources do not mention any investigation or conclusion by the FBI or DOJ regarding “New Jersey men detained after 9/11.” The packet contains no DOJ or FBI press release, report, or archive reference that states findings about New Jersey detainees from the post‑9/11 period; therefore any asserted conclusions about those detainees are unsupported by the supplied material (not found in current reporting) ^{[1] [3]}.

3. Where reporting in these sources does discuss 9/11 or counterterror work

The FBI’s historical summary of the 9/11 investigation describes the scope and consequences of the attacks—3,000 killed and significant changes to U.S. counterterror practices—without detailing individual detainee cases or state‑level detainee outcomes ^[3]. That page is broad and institutional rather than case‑specific ^[3].

4. Why the supplied DOJ items don’t answer the detainee question

DOJ District of New Jersey releases in the packet focus on contemporary criminal matters (fraud, narcotics, firearms, false reports) and attribute investigations to task forces that include FBI agents; they do not function as historical audits of post‑9/11 detentions or as records of findings about specific individuals held after 2001 ^{[1] [4] [5]}. The field‑office press pages similarly list recent press releases and case announcements, not archival analyses of early‑2000s detentions ^{[6] [8]}.

5. What additional documents would be needed to answer fully

To answer the question authoritatively you would need DOJ or FBI final reports, press releases, internal memos, Inspector General reviews, or court records explicitly addressing the arrests/detentions of New Jersey residents after 9/11 and the agencies’ investigative conclusions. None of those specific record types appear in the provided search results (not found in current reporting) ^{[1] [3]}.

6. Competing perspectives and limitations in the provided packet

The packet includes contemporary prosecutorial messaging that credits multi‑agency task forces (an implicit perspective that federal and local law enforcement collaborate on threats and crimes) but contains no material reflecting civil‑liberties, congressional oversight, or independent reviews of post‑9/11 detention practices in New Jersey. Oversight documents cited elsewhere (for example, congressional correspondence about DOJ investigations) appear in the result list but do not reference New Jersey detainees specifically in the supplied snippets ^[9]. Therefore the materials reflect the perspective of prosecutorial press releases and institutional history, not independent adjudication of detainee treatment or exoneration.

7. Bottom line for readers

Based on the files you provided, there is no DOJ/FBI statement about “New Jersey men detained after 9/11.” To proceed, request specific names, dates, or provide additional documents (DOJ press releases, FBI statements, Inspector General reports, or court records) so the inquiry can be matched to concrete reporting or official findings. Current sources show DOJ and FBI activity in New Jersey on recent cases and an institutional 9/11 history, but they do not address the question posed ^{[1] [6] [3]}.
