The United States appeals the district court’s order granting Defendant James Johnson’s motion to suppress a shotgun found during a warrantless search of his residence. The appeal is taken pursuant to 18 U.S.C. § 3731. We REVERSE.
I.
On the night of July 4, 2002, officers of the Grand Rapids police department responded to a report that a man was firing a shotgun from a porch of a home on Sigsbee in Grand Rapids, an area of two-story homes. The dispatch report indicated residents of the home included children. On arriving, officers saw a black male sitting on the front porch of 813 Sigsbee with a long gun on his lap. He was wearing a jersey bearing the number 05 and a bandana. As the officers watched, the man stood up, discharged the firearm into the air twice, and then reloaded it. The officers then heard someone say “police,” and *365saw the man quickly turn and flee into the house through the front door.
The officers requested backup. Within minutes more officers arrived and surrounded the house. Several officers approached the front door and knocked numerous times, shouting to the occupants to answer the door. Although they heard muffled voices and rustling noises from within, the officers did not receive an answer. Not knowing the number of occupants in the house, whether they included children or if they had been taken hostage, or the identity of the shooter and whether he also lived there, the officers forced open the front door and entered the residence.
Upon entry, the officers immediately observed a shirtless, bareheaded black man, who was later identified as the shooter, and a woman in the kitchen area. The officers did not see the gun. Two officers immediately ran upstairs to search for the armed suspect and to determine if there were other occupants. In the meantime, other officers secured the man and the woman, having them lie on the living room floor, and then searched the remainder of the main floor for the armed suspect or additional occupants. During this search, and less than one minute after entry, officers discovered a loaded 12-gauge semiautomatic shotgun in a large pantry closet, adjacent to the kitchen, approximately eight to fifteen feet from where the man and woman had been found. The shotgun was within plain view when the closet door was opened. A short time later, the “05” jersey was found on the living room floor. No other persons were found in the home. This search lasted just two to three minutes.
Johnson was arrested at that point for violating state misdemeanor laws and city ordinances. The officers did not obtain an arrest warrant before entering the home to arrest Defendant. Nor did the officers obtain a search warrant prior to searching the house.
At the time of his arrest, the officers did not know Defendant was a convicted felon. Upon that discovery, on July 25, 2002, he was indicted on federal charges for being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1). On February 25, 2003, Defendant filed a motion to suppress the gun evidence, arguing that the shotgun was found in an unconstitutional search and seizure. After a hearing, the district court granted Defendant’s motion. The United States appeals.
II.
This Court reviews a district court’s ruling on a suppression motion under a mixed standard of review. United States v. Akridge, 346 F.3d 618, 622 (6th Cir.2003). The district court’s factual findings are reviewed for clear error, but we review its conclusions of law de novo. Id.
III.
In a confusing bench ruling that cited no authority, the district court initially concluded that the warrantless entry was justified because the officers “had the right to pursue the individual to reasonably ascertain who it was and make an arrest for the misdemeanor committed in their presence.” The district court then found that officers determined “very quickly” that Defendant was the shooter. The court noted that, although Defendant was bare-chested, the jersey he had been wearing was lying on the floor. The district court also found that there was no reason to believe that there was anyone else in the house. Because the district court viewed this case as one involving a “protective sweep” to search for a weapon following an arrest, and because the arrest was for a misdemeanor and not for a felony, the *366court ruled that the warrantless search for the gun was unconstitutional. The court therefore suppressed the shotgun.
First, we think the district court misunderstood the nature of the protective sweep doctrine. Under the protective sweep doctrine, officers may quickly look into closets and other places in close proximity to the place of an arrest, after they have secured a suspect, to search for other persons who could launch an attack. See Maryland v. Buie, 494 U.S. 325, 334, 110 S.Ct. 1093, 108 L.Ed.2d 276 (1990). This may be done as a mere precaution and officers need not have reasonable suspicion or probable cause to do so. Id. Protective sweeps, therefore, generally involve searches for persons other than an arrestee. The district court cited no authority, and we have found none, to support the view that a protective sweep' — under circumstances in which the officers have observed the suspect firing and reloading a shotgun and then fleeing into the house, the occupants of which are unknown to the officers — would be unconstitutional simply because the eventual arrest was only for a misdemeanor. However, searches of places within the arrestee’s immediate area of control to find weapons are also permissible to protect officers from an arrestee who might gain possession of a nearby weapon. See Chimel v. California, 395 U.S. 752, 763, 89 S.Ct. 2034, 23 L.Ed.2d 685 (1969).
Thus, even if the officers believed that they “had their man” when they seized defendant, they still had the authority to conduct a protective sweep to search for other persons. And, they were authorized to search the immediate vicinity for weapons. Here, the pantry closet was both large enough to hide a man and near enough to be accessible to Defendant. Under such facts, the officers would have discovered the shotgun during a valid protective search. It therefore would have been admissible under the protective sweep doctrine.
Nevertheless, we think this case is better characterized as one involving a search for a suspect where a gun was found in plain view incident to that search. We view the facts of this case as falling within the hot pursuit and risk of danger exceptions to the warrant requirement. The Fourth Amendment to the United States Constitution protects the people “against unreasonable searches and seizures.” U.S. Const, amend. TV. Absent exigent circumstances, warrantless searches and warrantless seizures of evidence within a home are presumptively unreasonable. Payton v. New York, 445 U.S. 573, 587-88, 100 S.Ct. 1371, 63 L.Ed.2d 639 (1980). The exigent circumstances permitting warrantless entries of homes generally fall into four categories: “(1) hot pursuit of a fleeing felon, (2) imminent destruction of evidence, (3) the need to prevent a suspect’s escape, and (4) a risk of danger to the police or others.” United States v. Rohrig, 98 F.3d 1506, 1515 (6th Cir.1996) (citing United States v. Johnson, 22 F.3d 674, 680 (6th Cir.1994)).1 *367Importantly, seizures of items that are in plain view and made after entries under exceptions to the warrant requirement are legitimate. See Horton v. California, 496 U.S. 128, 134-35, 110 S.Ct. 2301, 110 L.Ed.2d 112 (1990) (quoting Coolidge v. New Hampshire, 403 U.S. 443, 465-66, 91 S.Ct. 2022, 29 L.Ed.2d 564 (1971)).
Here, the district court found that the officers determined “very quickly” that Defendant was the shooter, as if officers had immediately arrested Defendant and had no reason to look for anyone else. However, Defendant was only recognized as the shooter after the police determined no other persons were in the house and the shotgun had already been found. Upon entry, the man discovered in the kitchen was shirtless, bare-headed, and unarmed. Thus, there was ample reason for the officers to believe the actual suspect might be someone other than the arrestee and that he was somewhere else in the home. Indeed, it was entirely appropriate for the police to immediately continue looking for an armed man fitting the description of the man they had seen flee into the home. Moreover, although Defendant was secured immediately after entry into the home, no testimony established the timing of Defendant’s arrest as the perpetrator prior to the continuation of the search for the suspect. In fact, when asked on cross-examination whether they were looking for the gun, one officer testified that he was looking for armed suspects or victims, thereby denying that he had been searching for the gun. The other officer also never testified that he had been searching for the gun, indicating instead that he was searching for other people including “victims and casualties.” In sum, the district court’s ruling is based on two erroneous factual assumptions: (1) that the officers knew immediately that they had the gunman, and (2) therefore, if they kept searching it must have been to look for the weapon. The facts clearly do not support such assumptions.
The facts instead support application of the first category of exigent circumstances — hot pursuit. Warden v. Hayden, 387 U.S. 294, 298-99, 87 S.Ct. 1642, 18 L.Ed.2d 782 (1967) (involving hot pursuit of an armed felon into an occupied home). As our Supreme Court has made plain, “[t]he Fourth Amendment does not require police officers to delay in the course of an investigation if to do so would gravely endanger their lives or the lives of others.” Id. at 298-99. The Hayden Court also made clear that the permissible scope of a search for an armed suspect in a home must at least “be as broad as may reasonably be necessary to prevent the dangers that the suspect in the house may resist or escape.” Id. at 299. Although the Supreme Court has focused on the nature of the crime and upheld warrantless entries into homes in search of felons, as in Hayden, it has not completely foreclosed the possibility that such entries may be made to search for misdemeanants. See, e.g., Welsh v. Wisconsin, 466 U.S. 740, 753, 104 S.Ct. 2091, 80 L.Ed.2d 732 (1984) (noting that such entries are “rarely” sanctionable for minor offenses). Thus, the fact that this case involves the commission of misdemeanors, rather than the more usual situation involving felonies, does not render the hot pursuit doctrine inapplicable.
As in Hayden, this case involves the seizure of evidence found during a search for an armed suspect in the home into which he had fled after committing a crime. The police were not sure the man *368in the kitchen was the suspect they were looking for and reasonably continued their search for the suspect. Opening the door to a large pantry closet to look for him was reasonable because the closet was large enough to hide a man. The shotgun was in plain view once the door was opened. Thus, the warrantless entry in search of the suspect was constitutional under the exigency of hot pursuit. Because the shotgun was found and seized incident to the search for the gunman, as was the evidence in Hayden, it is admissible evidence. See also Horton, 496 U.S. at 134-35; cf. United States v. Bass, 315 F.3d 561, 564 (6th Cir.2002).
Additionally, the fourth category of exigent circumstances — when there is a risk of danger to the police or others, see Minnesota v. Olson, 495 U.S. 91, 100, 110 S.Ct. 1684, 109 L.Ed.2d 85 (1990) — also applies here. Under the circumstances of this case, the officers had ample justification for fearing for their own safety and especially the safety of others who might now be in the house with this reckless gunman. There had been a report of a man firing a gun from the porch in a residential neighborhood and that children resided there. Officers who responded to the call observed a man recklessly fire two shots into the air, reload the shotgun, and then fl.ee into the house. The officers did not know whether the man lived at the house, whether there were other occupants inside, or whether such occupants were hostages. The man had already demonstrated his willingness to repeatedly fire the shotgun and had apparently fled into the house only upon becoming aware of the police. That the man turned and fled into the home armed, rather than dropping the weapon and talking to the officers, created the potential for the incident to escalate into a deadly confrontation that could have involved hostage-taking. From the officers’ vantage point, this was a dangerous situation. Police are not required to wait for injury or death to occur in their presence before acting to protect people from a gunman who has amply demonstrated his propensity to use his weapon. Thus, the risk of danger was an exigent circumstance that also amply justified the officers’ warrantless entry into the house and the seizure of the shotgun was permissible under Horton.
In sum, on these facts, we hold that the shotgun should not have been suppressed.2
IV.
For the foregoing reasons, we REVERSE the district court’s order granting Defendant’s motion to suppress and REMAND the case to the district court for further proceedings.
. In Rohrig we recognized that these are not the only exigencies. Rohrig, 98 F.3d at 1521. When one of the traditional exigent circumstances does not exist, warrantless entries into a home may nevertheless be justified by examining "(1) whether immediate government action was required, (2) whether the governmental interest was sufficiently compelling to justify a warrantless intrusion, and (3) whether the citizen's expectations of privacy was diminished in some way.” Id. Here, immediate action was required because an armed man, who had already fired the shotgun and reloaded it, then fled into a house thought to be occupied. It was a compelling governmental interest to protect the occupants from harm, especially if they were children, as reported. And, defendant’s expecta*367tion of privacy was diminished because he had fired his weapon outdoors where any passerby could witness his unlawful conduct.
. Even if the search in this case was unconstitutional, however, the shotgun is admissible evidence because it inevitably would have been discovered by lawful means. See Nix v. Williams, 467 U.S. 431, 444, 104 S.Ct. 2501, 81 L.Ed.2d 377 (1984); United States v. Kimes, 246 F.3d 800, 804-05 (6th Cir.2001). The officers had probable cause to believe that the shotgun was in the house because they had witnessed Defendant shoot it from the porch, reload it and then flee into the house with it. Had it not been found in the search for the suspect, the officers would have obtained a warrant after they secured the house. Inevitably, they would have found the shotgun upon opening the pantry closet door. Thus, application of the exclusionary rule would not be appropriate here.
