Bеnjamin Garcia-Garcia was convicted of illegal re-entry into the United States after having been deported, in violation of 8 U.S.C. § 1326(a), and knowingly transporting illegal aliens, in violation of 8 U.S.C. § 1324(a)(1). He challenges the traffic stop which led to his arrest, contending that it was not supported by probable cause and was therefore in violation of his rights under the Fourth Amendment. We affirm.
I.
In the early evening of April 15, 2008, State Trooper Dustin Weiss was patrolling Interstate 55 nеar Springfield, Illi *610 nois. Trooper Weiss was parked on the median of the highway facing northbound traffic when he noticed a red Ford minivan traveling more slowly than the vehicles around it, under the posted speed limit of sixty-five miles per hour. As the van passed him, the trooper saw an air freshener hanging from the rearview mirror. The air freshener was tree-shaped, approximately five inches by three inches at its widest points, and bright pink and white in color. Photоs of the van taken at the scene reveal that the air freshener was easily discernable from outside the van. A baby-sized sandal was suspended below the air freshener, and the whole assembly stretched from the mirror to just short of the dashboard. 1 Illinois law prohibits a driver from operating a vehicle “with any objects placed or suspended between the driver and the front windshield, rear window, side wings or side windows immediately adjacent to each side оf the driver which materially obstructs [sic] the driver’s view.” 625 ILCS 5/12 — 503(c). 2 Believing the van to be in violation of that statute because of the air freshener, Weiss initiated a traffic stop. At a hearing to suppress the evidence that was the fruit of this stop, Weiss candidly admitted that he does not stop all vehicles with air fresheners but chose to pull over this van because of its slow speed, because the driver did not look at him as he passed, and because the drivеr appeared stiff, rigid and nervous. 3
The driver of the van was Benjamin Garcia-Garcia. When Trooper Weiss asked him for identification, Garcia-Garcia produced a Mexican identification card. Garcia-Garcia spoke “broken” English, according to Weiss, and the two had difficulty communicating. There were nine passengers in the van, all Hispanic. A few of them spoke enough English for Trooper Weiss to determine that the driver did not have a valid driver’s license and that all of the passengers were Mexican citizens illegally present in the United States. Trooper Weiss checked his computer for outstanding warrants and criminal history for Garcia-Garcia. He explained to Garcia-Garcia that he stopped the van because of the obstructed windshield. He issued to Garcia-Garcia a “Stop Card and Written Warning,” (hereafter “Warning Ticket”), containing the handwritten notation that the offense was “12-503(c) OBSTRUCTED WINDSHIELD.” The trooper also called his dispatcher and asked him to contact Immigration and Customs Enforcement (“ICE”).
An ICE agent arrived and confirmed that the driver and all of the passengers were present illegally in the United States. *611 The ten were then taken to the Springfield ICE office for questioning. After receiving Miranda warnings, Garcia-Garcia waived his right to an attorney and agreed to answer questions. He admitted driving the passengers frоm Phoenix, Arizona to Springfield, Illinois, where the van was stopped. He also told ICE officials that he knew his passengers were aliens who were present illegally in the United States. The passengers similarly waived their rights and admitted that they entered the United States without inspection. The passengers had paid (or were going to pay) between $1500 and $2000 each to be taken to destinations inside the United States.
Garcia-Garcia was charged with being prеsent without permission in the United States after previously having been deported, in violation of 8 U.S.C. § 1326(a), and with knowingly transporting illegal aliens within the United States by means of a motor vehicle, in violation of 8 U.S.C. § 1324(a)(1). Garcia-Garcia moved to suppress all evidence and statements obtained as a result of the traffic stop. The evidence Garcia-Garcia sought to suppress included the van, the passengers determined to be illegal aliens, cash found in Gareia-Garcia’s possession, and Trooper Weiss’ identification of Garcia-Garcia as an illegal alien. At a hearing before a magistrate judge, Trooper Weiss and Garcia-Garcia were the only two witnesses to testify. Garcia-Garcia argued before the magistrate and later in the district court that Trooper Weiss could not have seen the small air freshener from his vantage point given the speed at which the van was traveling. He also contended that Trooper Weiss could not reasonably have believed that the small air freshener was a “material” obstruction. The magistrate judge found Trooper Weiss to be credible and rejected Gareia-Garcia’s version of events. The magistrate judge found that Trooper Weiss saw the air freshener as the van passed his squad car. The magistrate judge further found that nothing in the record indicated Trooper Weiss was mistaken about the law, and noted Illinois cases in which the court found that an air freshener could constitute a material obstruction. The magistrate therefore recommended that the district court deny the motion to suppress. On
de novo
review, the district court also concluded that Trooper Weiss saw the air freshener and stopped the van based on his belief that the obstruction violated Illinois law. The court noted that the tеst for probable cause is an objective analysis conducted from the view of the reasonable officer under the circumstances at the time of the event. The court found that a reasonable officer could have concluded that the driver of the van committed a traffic violation. The court noted that the air freshener hung down in the driver’s line of vision, and that this court had previously concluded that an air freshener hanging from a rearview mirror could constitute a material obstruction in violation of Illinois law.
See United States v. Smith,
II.
On appeal, Garcia-Garcia abandons his claim that Trooper Weiss did not observe the air freshener. He argues only that no reasonable officer could have believed that this air freshener constituted a material obstruction, and that Trooper Weiss made a mistake of law in believing
*612
that
any
obstruction of a windshield would violate Illinois law when only a material obstruction is prohibited. If the trоoper did not have probable cause to believe that Garcia-Garcia violated the Illinois statute on material obstructions, there were no other legitimate reasons for the traffic stop, he argues, and any evidence procured from the stop should be suppressed. After oral argument in this appeal, Garcia-Garcia was released from prison and deported to Mexico. As a result, before addressing the substance of the case, we must first consider whether the appeal is moot.
United States v. Larson,
In reviewing the district court’s deniаl of a motion to suppress, we review questions of law
de novo
and factual findings for clear error.
United States v. Groves,
The prosecution bears the burden of proving by a preponderance of the evidence that a warrantless stop is supported by probable cause.
United States v. Basinski,
We begin by examining the trooper’s testimony regarding the traffic stop. At the suppression hearing, Trooper Weiss testified that, as the van approached his squad car, he “could see an air freshener hanging from the rearview mirror of the vehicle.” Tr. at 9. He decided to pull the vehicle over:
Q. What was the reason for the traffic stop?
A. For the obstructed view violation.
Q. That was for the?
A. The air freshener.
Tr. at 9. In testifying about issuing the Warning Ticket to Garcia-Garciа, Weiss testified:
Q. What does — what was this citation written for?
A. This was — the stop card warning was for the obstructed windshield, the reason why I stopped him.
Tr. at 13. The cross-examination focused largely on whether the trooper could have credibly seen the air freshener given his distance from traffic and the speed at which the van was traveling. The trooper confirmed that he witnessed no traffic violations other than the obstructed windshield, and conceded that he did not stop every car with an аir freshener. He explained that this car drew his attention because of its low speed and the rigid appearance of the driver. On re-direct, the prosecutor again asked Weiss about air freshener:
Q. Trooper, is it your testimony that as the vehicle approached you northbound, you saw the air freshener in the windshield?
A. Correct.
Q. And seeing that, you believed that a violation of the Illinois code was taking place?
A. Yes, sir.
Q. And that was the justification for the traffic stop?
A. Correct.
Tr. at 27-28. In addition to the trooper’s testimony, the Warning Ticket itself was admitted into evidence as were the air freshener and photos of the van taken at the time of stop. The photos display the size and position of the air freshener relative to the driver’s seat. As we noted above, the Warning Ticket bore the trooper’s handwritten notation that the offense was “12-503(c) OBSTRUCTED WINDSHIELD.” Section 12-503(c) prohibits a driver from operating a vehicle with any object suspended between the driver and
*614
the front windshield which “materially obstructs the driver’s view.” The facts known to Trooper Weiss, then, included the presence of an air freshener of the size we described, hanging in the driver’s line of vision as shown in the photographs. The district court found Trooper Weiss to be credible and credited all of his testimony. We must defer to those findings of fact unless they are clearly erroneous.
Groves,
In fact, this court has concluded in similar circumstances that an air freshener could constitute a mаterial obstruction in violation of Illinois law.
See United States v. Smith,
Gareia-Garcia argues that, under Illinois case law, no officer could reasonably believe that the air freshener constituted a material obstruction. Citing
People v. Cole,
The Illinois courts have come to differing conclusions in air freshener cases, depending on whether the officer properly understood the law and depending on the size, placement and mobility of the air freshener at issue. An officer’s belief that any obstruction larger than a thumbnail violated the statute was found to be a mistake of law.
People v. Mott,
In
People v. Johnson,
From these cases we conclude that air fresheners may (or may not) constitute material obstructions depending on their size, their position relative to the driver’s line of vision, and whether they are stationary or mobile. In this case, in addition to the trooper’s testimony, the government entered into evidence the air freshener itself, the Warning Ticket, and photos of the air freshener hanging in the van. The object the trooper observed was small, but
*616
given its size and position relative to the driver, a reasonable officer could conclude that it violated the Illinois statute prohibiting material obstructions. That reasonable belief is all that is needed to justify the warrantless stop.
See Carmichael v. Village of Palatine,
Finally, we note that even a successful challenge to the stop would not result in the suppression of the most imрortant evidence that Garcia-Garcia seeks to exclude. “The ‘body’ or identity of a defendant or respondent in a criminal or civil proceeding is never itself suppressible as a fruit of an unlawful arrest, even if it is conceded that an unlawful arrest, search, or interrogation occurred.”
INS v. Lopez-Mendoza,
Affirmed.
Notes
. Trooper Weiss testified that he did not seе the sandal until after he stopped the van. In the black-and-white photos of the van that appear in the record, the sandal appears to be similar in size to the air freshener but blends in with the background. Because Weiss testified that he did not see the sandal before effecting the stop, the district court did not consider it in determining whether probable cause existed to stop the van; we will follow suit.
. The title of Section 12-503 is "Windshields must be unobstructed and equipped with wipers."
. Driving carefully and within lawful parameters does not generate reasonable suspicion or probable cause in the ordinary case.
See United States v. Ingrao,
. We say "largely irrelevant" rather than simply "irrelevant" because of the Supreme Court’s admonition that, "[o]n occasion, the motive with which the officer conducts an illegal search may have some relevance in determining the propriety of applying the exclusionаry rule.”
