Mahon v. United States, 2:17-cv-02031

Background

In 2004 a pipe bomb exploded at Scottsdale’s Diversity Office, severely injuring the director and others; after a multi‑year undercover investigation Dennis Mahon was charged and convicted on three counts relating to the bombing and distribution of explosive‑making information.
Mahon received concurrent sentences: 40 years on Counts 1 and 2 (conspiracy and malicious damage by explosive) and 33 months on Count 3 (distribution of explosive‑making information).
Mahon filed an amended 28 U.S.C. § 2255 petition raising ineffective‑assistance and other claims; Magistrate Judge Metcalf issued an R&R recommending denial; Mahon objected on four principal grounds asserting counsel was ineffective.
The contested issues on objection: (1) appellate counsel’s failure to appeal denial of motion to suppress statements made in a police van (Miranda/functional‑equivalent interrogation); (2) appellate counsel’s failure to appeal admission of co‑defendant Daniel’s recorded statements (Confrontation/Bruton); (3) failure to obtain dismissal of Count 3 for entrapment and trial counsel’s withdrawal of an entrapment jury instruction; and (4) appellate counsel’s failure to appeal application of a 12‑level terrorism enhancement at sentencing.
The district court accepted the R&R, reviewed Mahon’s objections, and denied the § 2255 motion, finding counsel’s choices were reasonable and Mahon failed to show prejudice under Strickland.

Issues

Issue	Plaintiff's Argument (Mahon)	Defendant's Argument (Government)	Held
1) Appellate counsel ineffective for not appealing denial of motion to suppress van recordings (Miranda/functional‑equivalent interrogation)	Agents used psychological ploys, placed defendants in a hot wired van for hours, and orchestrated interactions (via Agent Moreland and Daniel) that were the functional equivalent of interrogation; reasonable probability of success on appeal	Officers’ statements were "normally attendant to arrest," the van conditions were promptly remedied and not coercive, defendants expected recording, and no questioning occurred that was likely to elicit incriminating responses	Court held counsel reasonably declined appeal; no Strickland prejudice because interactions did not amount to Miranda interrogation and an appeal was unlikely to succeed
2) Appellate counsel ineffective for not appealing admission of Daniel’s van statements under Confrontation Clause/Bruton	Daniel’s recorded statements implicated Mahon and, absent co‑conspirator theory, Bruton/Larson should have barred their admission	Daniel’s statements were non‑testimonial; Crawford/Davis/Whorton permit admission of non‑testimonial statements and Larson post‑en banc confirms no Confrontation violation	Court held appeal would have failed; statements were non‑testimonial so Confrontation Clause did not bar admission; no Strickland prejudice
3) Entrapment (pretrial dismissal / trial counsel withdrawal of entrapment instruction)	Government induced Mahon through months of pressure by a confidential informant (Rebecca Williams); Mahon lacked predisposition and Count 3 should have been dismissed or an instruction given	Evidence showed Mahon suggested bomb construction, showed little reluctance, and had character/reputation and statements supporting predisposition; counsel reasonably withdrew instruction to avoid permitting rebuttal evidence on Counts 1–2	Court held entrapment dismissal was not required as factual disputes existed; trial counsel’s tactical withdrawal was reasonable and, even if error, no prejudice because evidence supported predisposition
4) Appellate counsel ineffective for not appealing 12‑level terrorism enhancement (U.S.S.G. § 3A1.4)	Enhancement inappropriate because the conduct did not constitute federal terrorism aimed at influencing federal government (issue ripe for appeal)	Circuits (and Ninth Circuit analogues) interpret § 3A1.4 to apply when offense was calculated to influence or affect government by intimidation or to retaliate; intent to affect municipal government suffices and appellate success was unlikely	Court held counsel reasonably declined appeal; Mahon failed to show a substantial likelihood of a different result on appeal
