BILLY CANNON,                                    Appeal from the United States District

                                        ORDER

       This appeal arises out of a search of the prison cell of Wisconsin prisoner Billy
Cannon. Cannon believes that the search was initiated unlawfully by a Milwaukee
police officer, Dean Newport, in retaliation for Cannon’s petitioning to have a “John
Doe investigation” (a unique Wisconsin procedure that resembles a grand jury
investigation) opened against Newport to expose his wrongdoing. The district judge
entered summary judgment in favor of Newport, concluding that there was no evidence

         We have agreed to decide the case without oral argument because the briefs and
record adequately present the facts and legal arguments, and oral argument would not
significantly aid the court. FED. R. APP. P. 34(a)(2)(C).
No. 17-2753                                                                            Page 2

the officer knew about the petition before seeking the cell search. We affirm the
judgment.

        As Cannon alleged in his federal complaint, Newport asked prison officials to
search his prison cell after finding out that Cannon had named him in a petition seeking
a “John Doe investigation.” Such proceedings, which are supervised by a judge, are
used to determine whether a crime has been committed. See WIS. STAT. § 968.26; John K.
Maciver Inst. for Pub. Policy, Inc. v. Schmitz, 885 F.3d 1004, 1007–08 (7th Cir. 2018). In his
John Doe petition, Cannon, who at the time was serving a prison sentence and awaiting
trial on another criminal case, had asserted that Newport and other law-enforcement
officials conspired to “frame” him for crimes that led to both the sentence he was
serving at the time and his pending charges. Several weeks after filing this petition,
Cannon alleged, his prison cell was searched and legal documents from his cell were
seized by prison officials.

        At the screening stage, see 28 U.S.C. § 1915A, the district judge dismissed several
of Cannon’s claims for failure to state a claim, including that Cannon’s cell was
searched and his documents seized in violation of the Fourth Amendment. The judge
concluded that Cannon did not have a reasonable expectation of privacy in his prison
cell. But the judge allowed Cannon to proceed on a claim that Newport violated the
First Amendment by retaliating against him for engaging in free speech, namely, filing
a John Doe petition.

       Both sides moved for summary judgment, and a fuller picture emerged of the
events leading up to the search of Cannon’s cell. (We review these facts de novo and
draw all inferences in Cannon’s favor, see Austin v. Walgreen Co., 885 F.3d 1085, 1087
(7th Cir. 2018)). In addition to his John Doe petition against Newport and other
law-enforcement agents, Cannon had filed an unrelated John Doe petition to investigate
wrongdoing by the state trial judge who presided over both of his criminal cases,
Judge Michael Guolee. In that petition, Cannon alleged that Judge Guolee had
sentenced him to prison out of jealousy because the judge’s clerk, Tammy Baldwin, had
been having an affair with both the judge and Cannon during Cannon’s prosecution.

       Judge Guolee’s alleged bias also was the subject of a motion to vacate the prison
sentence Cannon was serving. In the motion, Cannon reiterated that his sentence
stemmed from Judge Guolee’s jealousy over his relationship with Baldwin. Cannon
attached to his motion love letters that Baldwin sent to him in prison, ostensibly to
prove the existence of his relationship with Baldwin.
No. 17-2753                                                                         Page 3

       The contents of Cannon’s motion to vacate—and particularly the accompanying
love letters from Baldwin that contained references to Cannon’s criminal cases—caught
the attention of various county offices, including the Milwaukee County District
Attorney’s Office. That office began investigating whether Baldwin had inappropriately
passed confidential information to Cannon during their relationship. An investigator
from the District Attorney’s Office contacted Newport to assist that effort.

        Less than a month after Cannon filed his motion to vacate, Newport contacted
the prison’s security director to request a search of Cannon’s prison cell to determine if
Cannon possessed any sealed documents that might have come from Baldwin. When
Newport eventually reviewed the seized documents, he found copies of the same love
letters from Baldwin that had sparked the investigation, but nothing else noteworthy.

       Newport asserted in a declaration that he sought to search Cannon’s cell solely
on the basis of Baldwin’s letters and the allegations in Cannon’s motion to vacate, and
not on the basis of the John Doe petition filed against him. Newport denied knowing
anything of the John Doe proceedings, which, unlike Cannon’s motion to vacate, were
not a matter of public record.

       The district judge entered summary judgment for Newport, concluding that
Cannon had produced no evidence that his request for a John Doe investigation
induced Newport to order a search of his cell. Cannon, the court said, provided no
evidence to show “what the defendant knew or when he knew it,” and Cannon’s
“unsupported opinions and beliefs” about Newport’s retaliatory intent were
insufficient to create a fact question. Further, the judge rejected Cannon’s request to
reinstate his Fourth Amendment claim in light of Manuel v. City of Joliet, 137 S. Ct. 911
(2017), in which the Court held that the Fourth Amendment provides a cause of action
for unreasonable seizure of a pretrial detainee. The judge determined that Cannon was
a convicted prisoner rather than a pretrial detainee at the time his cell was searched, so
Manuel did not apply.

       On appeal Cannon maintains generally that Newport was aware of the John Doe
petition filed against him, and that the petition motivated him to retaliate by searching
Cannon’s cell and seizing documents. In support, Cannon identifies what he regards as
“circumstantial evidence” of Newport’s retaliatory intent that the district judge
overlooked. For example, Cannon highlights what he describes as Newport’s deceptive
misuse of federal-government stationery in correspondence thanking the prison’s
security director for his assistance in the search of Cannon’s cell. Despite being a
Milwaukee police officer, Newport—according to Cannon—lied about his position by
No. 17-2753                                                                         Page 4

writing the security director on stationery bearing official letterhead for the Bureau of
Alcohol, Tobacco, and Firearms. And if Newport was willing to lie about his own
official position, Cannon posits, he must also be lying about his motives for searching
Cannon’s prison cell. But Cannon’s argument is directly refuted by Newport’s
declaration, in which he explained that he was authorized to use the letterhead as a
deputized ATF agent. Cannon offers only his own speculation to rebut Newport’s
declaration, and speculation is not enough to raise an inference of a retaliatory motive.
Consolino v. Towne, 872 F.3d 825, 830 (7th Cir. 2017).

        Next, Cannon takes issue with the district judge’s dismissal of some of his claims
at screening (he does not specify which claims) and contends that the judge should have
allowed him to reassert them. At least, he seems to believe that he stated a Fourth
Amendment claim of an unreasonable search and seizure. But as the district judge
correctly observed, a convicted prisoner (as Cannon was at the time) has no reasonable
expectation of privacy in his cell. Hudson v. Palmer, 468 U.S. 517, 525–26 (1984);
see also King v. McCarty, 781 F.3d 889, 899 (7th Cir. 2015). Cannon argues that the
Supreme Court’s decision in Manuel alters this rule, but Manuel applies only to pretrial
detainees and does not address searches or seizures of property. See 137 S. Ct. 918–20.
Cannon also argues that he had an expectation of privacy as to searches conducted for
investigative purposes rather than for institutional-security reasons, but we have never
drawn such a distinction, and at least one court has specifically disavowed it. See Willis
v. Artuz, 301 F.3d 65, 68–69 (2d Cir. 2002).

      Cannon’s additional arguments are frivolous and merit no further discussion.

                                                                              AFFIRMED
