Robert Daniel Gassier and James Leroy Scott, plaintiffs-appellants, were both incarcerated at the Minnesota Correctional Facility at Oak Park Heights (MCF-OPH) when, on June 11, 1991, they initiated a pro se action pursuant to 42 U.S.C. § 1983 in the United States District Court for the District of Minnesota, 1 seeking injunctive, declaratory, and monetary relief from three MCF-OPH officials, Frank Wood, Steve Lydon, and Walter Sass, defendants-appellees. In their nine-count complaint, Gassier and Scott claimed, inter alia, that the defendants had violated their First and Fourteenth Amendment rights by providing a third party with photocopies of their nonlegal mail. On June 15,1992, the district court awarded summary judgment in the defendants’ favor on all counts except a state law count, which it dismissed without prejudice. See Gassler et al. v. Wood et al., No. 4-91-450 (D.Minn.1992). Gassier and Scott filed a timely notice of appeal. We affirm.
I.
On February 8, 1991, while Gassier and Scott were incarcerated at MCF-OPH, 2 a Todd County, Minnesota, grand jury indicted them for premeditated first degree murder, intentional second degree murder, and second degree murder while committing a felony in connection with the death of Dale William Yungk. Ricky Lowen, special agent for the Minnesota Bureau of Criminal Apprehension (BCA), was the chief investigator in the criminal charges brought against the appellants.
In an affidavit, Agent Lowen stated that in the course of his investigation he had “received information from several sources that Gassier and Scott were trying to intimidate and, in some cases, kill prosecution witnesses who would testify against them in their upcoming criminal trials.” Believing that Gassier and Scott were indeed willing to harm or threaten prosecution witnesses who would testify against them and that they had contacts outside of MCF-OPH who were in a position to carry out their requests, 3 Agent *408 Lowen said that he contacted Steve Lydon, Internal Affairs Liaison at MCF-OPH, on or about April 30, 1991, and asked that Gassier and Scott be separated if they were living next to one another. Lydon agreed to separate them. 4 Lydon also informed Agent Lowen that he (Lydon) could obtain authority to read Gassler’s and Scott’s nonlegal correspondence, and offered to provide Agent Lowen with photocopies of the correspondence. Believing that Gassier and Scott might use the mail in connection with plans to intimidate and harm prospective witnesses, Agent Lowen accepted Lydon’s offer to furnish him with photocopies.
Lydon thereupon secured authorization from Frank Wood, who was Warden of MCF-OPH at that time, to monitor appellants’ nonlegal correspondence and began to do so. Lydon would only skim the mail, after which he photocopied it and delivered the copies to Agent Lowen. Notwithstanding these practices, appellants’ incoming nonlegal correspondence was delivered to Gassier and Scott and their outgoing correspondence was sent on to addressees.
II.
On appeal, Gassier and Scott do not argue that appellees abridged any of their constitutional or legal rights by providing Agent Lowen with photocopies of their incoming nonlegal mail. Nor do they contend that providing Agent Lowen with copies of their outgoing nonlegal mail violated constitutional or legal rights other than free speech interests under the First Amendment. Gassier and Scott concede, moreover, that “appellees [prison authorities] were within their rights to monitor [their] outgoing nonlegal correspondence.” 5 Hence, the only issues on appeal are (1) whether the appellees trenched upon First Amendment free speech rights by delivering to Agent Lowen photocopies of Gassler’s and Scott’s outgoing nonlegal mail and, if so, (2) whether such an infringement was justifiable under these circumstances.
In
Procunier v. Martinez,
In the present case, unlike in
Martinez,
there was no censorship or other direct restraint. All of Gassler’s and Scott’s incoming mail was delivered to them uncensored, and their uncensored outgoing mail was sent along to its intended recipients. If Gassler’s and Scott’s First Amendment communicative rights were abridged at all, it would be because of the deterrent or “chilling” effect
*409
upon free expression caused by the authorities’ opening and examination of appellants’ mail, including transmittal of photocopies to Agent Lowen for his further examination.
See Laird v. Tatum,
Had the authorities improperly shared appellants’ outgoing mail with unauthorized persons — for example, with a newspaper reporter or a prisoner’s business rival — the situation might be different.
Cf Trudeau v. Wyrick,
Even, however, if letting Agent Lowen see the correspondence was a separate and greater intrusion upon First Amendment rights, appellees should still prevail. Restraints on inmate correspondence are justified in furtherance of “the legitimate governmental interest in the order and security of penal institutions.”
Martinez,
To be sure, the
Martinez
Court indicated that “the limitation of First Amendment freedoms must be no greater than is necessary or essential to the protection of the governmental interest involved.”
Id.
But the Court also stated that prison administrators need not “show with certainty that adverse consequences would flow from failure to censor a particular letter. Some latitude ... is essential to the proper discharge of an administrator’s duty.”
Id.
at 414,
Here, nothing was done to interfere with appellants’ correspondence other than reading it with the aid of the specially knowledgeable investigator, Agent Lowen. Appellants argue that the prison officials went too far in allowing Agent Lowen to see the outgoing correspondence, as his examination was not proven to be “necessary or essential” within Martinez. In appellants’ view, the prison liaison officer, Lydon, could have adequately detected any references in the correspondence to witness intimidation or murder. Agent Lowen, however, was positioned to read the letters in the context of his detailed knowledge of appellants’ outside activities and connections. Particular words, names, or phrases might have conveyed some meaning to Agent Lowen that would have been lost upon Lydon. Given the very serious nature of the suspected conduct, it was a sensible and justifiable precaution for the authorities to let Agent Lowen see the letters. Even under a strict and literal reading of Martinez, and without reference to other *410 cases, 6 we have no doubt that prison officials were entitled to enlist Agent Loweris expertise in screening the letters for the purpose of ascertaining whether appellants were engaging in the type of criminal activity that Agent Lowen feared.
Affirmed.
Notes
. The Honorable James M. Rosenbaum, District Judge, United States District Court for the District of Minnesota.
. Scott is serving a 125-month sentence for kidnapping and first degree assault as well as a consecutive life sentence for first degree murder. Gassier is serving a 145-month sentence for aggravated robbery and forgery. In June of 1992, Gassier was transferred to a federal facility in Oxford, Wisconsin.
.Agent Lowen stated in his affidavit that he was "familiar with [the appellants'] extensive criminal histories, in which both [men] had committed numerous crimes of violence against individuals whom they perceived as threats to the success of their plan.”
. Following his conversation with Agent Lowen, Lydon directed Lt. Walter Sass, the officer in charge of the MCF-OPH Segregation Complex, to move Gassier and Scott into different defend-able living units.
. Several circuits, including ours, have held that prison officials do not commit constitutional violations by reading prisoners’ outgoing nonprivileged mail.
