The Affidavit and the Informant
You supervise the detective bureau of a 110-officer New Jersey department. Detective Marsh submits a search-warrant affidavit for a residence. The affidavit says a confidential informant is 'reliable' and 'has provided information in the past,' and that the informant made a controlled buy of heroin at the residence. It does not mention that the informant has a pending theft charge, was paid $300, and was not searched before or after the buy. The buy was not recorded; the detective says the informant's car was 'not available' for a search. The warrant is signed. Officers find 40 grams of heroin, a handgun, and $2,000. The defendant's attorney files a motion alleging a Franks violation and demands the informant's identity and payment records. The detective asks you to back the affidavit.
1. Assess the affidavit. What facts support or defeat a Franks hearing?

A Franks hearing requires a substantial preliminary showing that the affiant knowingly or recklessly included a false statement, or omitted a material fact, and that the false or omitted fact was necessary to the probable-cause finding. Here, the omissions matter: the informant's pending theft charge creates a motive to curry favor, and the $300 payment is impeachment material. The 'reliable' label is a conclusion; the affidavit should state the basis for reliability. The failure to search the informant before or after the buy undermines the controlled-buy narrative because the informant could have obtained the drugs elsewhere. The lack of recording is not automatically fatal, but it weakens corroboration. The defense has a respectable argument for a hearing. Your job is not to back the affidavit blindly; review it line by line with the detective, identify what is supported by documented facts, and tell the prosecutor about the problems. If the detective exaggerated, that is a potential Brady/Giglio and internal-affairs issue, not just a litigation problem.
2. What are your disclosure obligations regarding the informant's pending charge and payment?
Read the worked answer
Brady and Giglio require disclosure of evidence favorable to the accused that is material to guilt or punishment, including impeachment evidence about a testifying witness. The informant's pending theft charge and the $300 payment are classic impeachment material if the informant testifies. New Jersey discovery under Rule 3:13-3 is broad, and the prosecutor, not the police, makes the final disclosure decision; your duty is to get the information to the prosecutor in writing and preserve it. Do not conceal the payment records or the informant's criminal history. If the informant will not testify, the analysis changes, but the defense may still be entitled to information that could lead to admissible evidence or support a Franks hearing. The detective should not destroy notes, texts, or payment records. Create an indexed file and send copies to the prosecutor with a cover memo. If the detective's affidavit was knowingly false, notify internal affairs and the prosecutor's professional standards unit; the department's credibility is more important than one case.
3. What case-management and supervisory steps do you take now?
Read the worked answer
Immediately pull the warrant file, the informant file, the buy-money records, and the detective's notes. Suspend any further warrant applications by Marsh pending review, not as punishment but to prevent a pattern. Notify the prosecutor's office and the chief. Interview the detective with a union representative if requested; ask for an explanation of the omissions before deciding whether this is sloppy drafting or dishonesty. Audit Marsh's other affidavits from the past year for similar language. Consider whether the department should adopt a search-warrant review checklist requiring supervisors to verify informant payments, criminal history, and buy procedures before submission. Document everything. In the criminal case, cooperate with the prosecutor's disclosure obligations; in the administrative case, follow the internal affairs process. Do not let the detective's request for backup turn into a loyalty test: your duty runs to the case, the defendant's due-process rights, and the department's credibility.
