McKEE, Chief Judge

        Appellants appeal the district court’s grant of summary judgment in the action

they filed pursuant to 42 U.S.C. § 1983 against the City of Harrisburg 1 and certain city

officials. For the reasons that follow, we will affirm.


1
 On October 11, 2011, the City of Harrisburg filed for Chapter 9 bankruptcy protection in the Middle District of
Pennsylvania, Case No. 11-06938. The case was dismissed on November 23, 2011. The City of Harrisburg
appealed the dismissal. On December 13, 2011, the City of Harrisburg’s notice of appeal was stricken by the
bankruptcy court due to the City of Harrisburg’s failure to file a timely appeal. On December 22, 2011, the City of
Harrisburg filed its notice of appeal of the December 13, 2011 order.


                                                         2
        We write primarily for the parties and therefore will only set forth those facts that

are helpful to our discussion of the issues. 2

        On September 2, 2007, Appellants were arrested for violating Harrisburg Park

Ordinance 10-301.20(a) ( the “Ordinance”) while attending an event on McCormick

Island in the Susquehanna River. Each of these appellants was held until arraignment

because of their out-of-state residence. Thereafter, they sued, alleging, among other

things, false arrest, violation of their First Amendment rights, violation of the Fourth

Amendment and their right to travel, as well as a claim for municipal liability. The

District Court adopted the Magistrate Judge’s Report and Recommendation, granted the

defendants’ motion for summary judgment, and dismissed the suit. This appeal followed.

                                          I. False Arrest Claims.

        To prevail on a false arrest claim under the Fourth Amendment, a plaintiff must

show that the police made an arrest without probable cause. Barna v. City of Perth

Amboy, 

, 819 (3d Cir. 1994). The test for an arrest without probable cause is

an objective one, based on “the facts available to the officer at the moment of arrest.” 

need only exist as to any offense that could be charged under the

circumstances. 

cause inquiry looks to the totality of the circumstances.

Wright v. City of Philadelphia, 

, 603 (3d Cir. 2005).



2
  The magistrate court had permission to hear the case pursuant to 28 U.S.C. § 636(b)(1)(B). The district court had
jurisdiction pursuant to 28 U.S.C. § 1331. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review a district
court's decision denying a motion for judgment as a matter of law de novo. Eddy v. V.I. Water & Power Auth., 

, 230 (3d Cir. 2004). We “apply the same standard that the District Court did, namely whether, viewing the
evidence in the light most favorable to the non-movant and giving it the advantage of every fair and reasonable
inference, there is insufficient evidence from which a jury reasonably could find liability.” 

certain exceptions not relevant here, the Ordinance prohibits participating in

an assembly of 20 or more persons “in any park” without first obtaining a permit.

Appellants’ attempt to claim that the arresting officers did not have probable cause to

believe that they were violating the Ordinance is patently frivolous. Police clearly had

reason to believe that more than 20 persons had assembled on the island. It is undisputed

that several hundred individuals were involved in the “party.” In fact, there are clearly

more than 20 plaintiffs involved in this suit. Although Appellants attempt to argue that

the island’s status as a “park” is a disputed issue of fact, it is undisputed that the island

contains a bird sanctuary. Accordingly, whether or not the island is a “park” within the

meaning of the Ordinance, it was certainly reasonable for the arresting officers to assume

that it was. Finally, there is absolutely nothing on the record that would have led the

officers to believe that the participants had obtained the required permit to participate in

the assembly on the island.

       A warrantless arrest is permissible “if there is probable cause to believe that the

suspect has committed or is committing an offense.” Mich. v. DeFilippo, 

, 36

(1979). Thus, the technical arguments Appellants make to challenge the ordinance do not

undermine the validity of these arrests because “[any] subsequently determined invalidity

of the . . . ordinance . . . [would] not undermine the validity of the arrest made for

violation of that ordinance.” 

       Moreover, since it is uncontested that each of these appellants lived out-of-state, it

is clear that police acted reasonably (and prudently) in briefly detaining them until they

could be arraigned. Thus, Appellants’ attempt to argue that the defendants’ conduct


                                               4
violated the right to travel is also meritless. See Jones v. Helms, 

, 419

(1981) (stating that “probable cause may justify an arrest and subsequent temporary

detention.”)

                                      II. Right of Assembly.

       We also agree with the District Court’s conclusion that the Appellants did not

adequately raise a violation of their First Amendment right to assemble by merely

referencing the issue in briefing and not substantively raising it prior to objecting to the

Magistrate’s Report and Recommendation. See Laborers’ Intern. Union of N. Am., AFL-

CIO v. Foster Wheeler Energy Corp., 

, 398 (3d Cir. 1994) (stating that “an

issue is waived unless a party raises it in its opening brief, and for those purposes ‘a

passing reference to an issue … will not suffice to bring that issue before the

court.’”)(internal citations omitted) We will, therefore, not consider Appellants’ First

Amendment argument on appeal.

                                     III. Void for Vagueness.

       Appellants’ attempt to argue that the Ordinance is somehow unconstitutionally

vague is also meritless. A statute or ordinance is unconstitutional “if it fails to provide

people of ordinary intelligence a reasonable opportunity to understand what conduct it

prohibits[,]” Hill v. Colo., 

, 732 (2000), or “if it authorizes or even

encourages arbitrary and discriminatory enforcement.” 

clearly gives

notice that people who wish to assemble in a “park” must obtain a permit if they believe

that the resulting assembly will consist of more than 20 people. It is hard to imagine how

the Ordinance could be any clearer.


                                              5
        Accordingly, for the reasons state above, we will affirm the District Court’s grant

of summary judgment. 3




3
 We need not address Appellants’ municipal liability claim or the issue of qualified immunity because there was no
constitutional violation.
