On August 13, 2000, Arlease Prevo drove her car to the Loxley Work Release Center, a correctional facility in Alabama. She went there to pick up an inmate, Derrick Wise, who was serving a ten-year sentence on drug charges; he had an eight-hour pass permitting him to leave the center. Twice in the preceding two weeks (on July 30 and August 6) Prevo had driven to the facility, signed out Wise on eight-hour passes, and then driven him back when he was due to return. On three other occasions earlier in the year (April 30, May 14, and May 28), Prevo had driven to the center and visited Wise there. All told, in the preceding three- and-a-half months Prevo had driven her car onto the work release center property on seven occasions.
On this occasion, as on all sеven previous ones, when Prevo drove off the public roadway through the entrance to the center property, she drove past two large signs, one above the other, that were posted on the right side of the entrance, just off the roadway. The top sign was approximately three feet high and four feet wide, and it stated in three-and-a-half inch capitаl letters:
ANY
VEHICLE BEYOND THIS POINT IS SUBJECT TO SEARCH
Immediately below that sign hung another one that was approximately four feet high and four feet wide. It stated in two-and-a-half inch capital letters:
THE FOLLOWING ITEMS ARE NOT AUTHORIZED ON THIS PROPERTY
1.FIREARMS
2. ALCOHOLIC BEVERAGES
3. ILLEGAL OR NARCOTIC SUBSTANCES OF ANY KIND ANYONE TRANSPORTING OR POSSESSING THESE ITEMS WILL BE SUBJECT TO CRIMINAL PROSECUTION
The two signs stood by themselves, surrounded by no other potential distractions, in clear view of visitors coming onto the work release center property.
On this occasion, as on the seven previous ones, when Prеvo drove off the public roadway onto the work release center property, she passed the two signs and continued driving on a winding road ap *1345 proximately fifty yards to the parking lot, which is adjacent to the center’s buildings. There was a difference this time, however. On the seven earlier occasions Prevo had gone to the center, no one was conducting searches. This time law enforcement officers, with the help of drug detection dogs, were searching all vehicles ■ entering the visitor parking lot. ■ The primary purpose of this kind of search is to keep weapons and drugs out of the work release facility.
While Prevo was in her car, officers approached it. Sergeant Kerry Mitchum of the Loxley Police Department asked Prevo if she had any weapons or drugs'in the car. When she did not respond, he repeated the question. Prevo, with the engine of her car still running,' told Sergeant Mitchum that she wanted to leave. He told her it was too late to -leave and instructed her to turn off the engine and exit the vehicle.
Prevo complied and informed the officers that she had a gun in her purse on the front seat. It was a .22 Magnum five-shot revolver, loaded with two live and, three spent cartridges. With the help of drug detection dogs, the officers also found a crack pipe, crack cocaine, and $22,991.00 in cash in the trunk of the car.
Prevo was charged in a two-count indictment with possession of cocaine base, in violation of 21 U.S.C. § 844(a), and with possession of а firearm by an unlawful user of a controlled substance, in violation of 18 U.S.C. § 922(g)(3). She filed a motion to suppress, on Fourth Amendment grounds, the physical evidence that was seized and the statements she made to the officers about the search. The district court denied the motion. As part .of an agreement Prevo pleaded guilty to the gun charge, and the .drug charge was droppеd. Her plea was conditioned on retaining the right to appeal the district court’s denial of her motion to suppress.
This is her appeal of that denial. The only issue before us is whether the search of Prevo’s car on the work release center property violated her Fourth Amendment rights: We decide the issue de novo. All the relevant facts are undisputed.
The Fourth Amendment protects “[t]he right- of the people to be secure ... against unreasonable searches and seizures.” U.S. Const. Amend. IV. Generally, a search is reasonable under the Fourth Amendment when supported by a warrant or when the search fits within an established exception to the warrant requirement. The Fourth, Amendment reasonableness inquiry is a balancing test that weighs, the need for the search, including its likely effectiveness in averting potential harm to the public, against the degree and nature of the intrusion into a citizen’s privacy interests.
Mich. Dep’t of State Police v. Sitz,
As for the justification behind the searсh in this case, sometimes it is helpful to state
*1346
the obvious. Prisons house people who have proven themselves unable or unwilling to obey the law. Most prisoners have more than a passing acquaintance with illegal drugs. Dep’t of Justice, Bureau of Justice Statistics,
Substance Abúse and Treatment, State and Federal Prisoners, 1997
3-4 (Jan.1999) (eighty-three percent of state prisoners reported past drug use and fifty-seven percent reported using drugs in the month before their offense). Most of them are sociopaths.
See Eddings v. Oklahoma,
Because of the character of prisoners and the nature of imprisonment, corrections facilities are volatile places, brimming with peril, places where security is not just an operational nicety but a matter of life or death importance.
See Bell,
Of course, walls and posted signs cannot banish the Fourth Amendment from prisons, but the nature of inmate populations and the necessity of keeping contraband out of prison facilities doеs factor heavily in the determination of what is reasonable. As we, through our predecessor court, put it nearly thirty years ago: “That which would be unreasonable in the outside world may be indispensable within a prison.”
Newman v. Alabama,
Searching automobiles that come onto prison property is an obvious way to keep contraband away from prisons. Nonetheless, Prevo argues that searches of automobiles in the parking lot generally will be ineffective at a work release сenter where inmates are regularly allowed out on passes and there is no way to ensure that they will not have access to contra *1347 band off prison property. The standard of constitutionality, however, is not one of perfect effectiveness, and prison officials are not required to permit inmates to have more convenient access tо contraband simply because they cannot cut it off entirely.
The Supreme Court has instructed us that “the problems that arise in the day-today operation of a corrections facility are not susceptible of. easy solutions,” and “[p]rison administrators therefore should be accorded wide-ranging deference in the adoption and execution of poliсies and practices that in their judgment are needed to preserve internal order and discipline and to maintain institutional security.”
Bell,
Prevo also argues that searching automobiles in the parking lot is, unreasonable because the goal of keeping contraband out of a corrections facility can be attained by searching everyone, whether visitor or returning inmate, who enters the facility. Entrance searсhes are performed at this work release center, and Prevo says that is enough. We defer to the common sense judgment of corrections officials that two layers of searches, a double-tier of deterrence, is better than just one. Searches are not infallible because, among other things, those conducting them are not. More searches, or thе threat of them, provide more security .than fewer searches do.
Visitors are signed into and out of this detention facility on a regular basis. They enter and leave it through the visitors parking lot, as do inmates who are picked up and dropped off as part of the pass program, Even if we assume that Prevo was not attempting to smuggle the loaded pistol and coсaine into the center, it would have remained in her car (the pistol on the front seat), accessible to prisoners passing by who were inclined to wrongdoing. As the Sixth Circuit has noted, “an object secreted in a car, to which prisoners may have access, is a potential threat at all times after the car enters the [prison] grounds.”
Spear v. Sowders,
Prevo contends that “less intrusive” means of keeping contraband out of the work release center exist, and she suggests these: “sеarching visitors when they
*1348
enter the facility, searching residents when they return from off-site visits, not allowing residents in the parking lot, monitoring residents in the parking lot, and running drug dogs around cars parked in the parking lot.” Appellant’s Br. at 22. Suffice it to say that the Fourth Amendment does not require the least intrusive alternative; it only requires a reasonable alternative.
See Romo v. Champion,
On the other side of the scale is the privacy interest of the person who drives her automobile onto prison grounds to pick up an inmate. There is a diminished expectation of рrivacy in an automobile to begin with.
See Pennsylvania v. Labron,
Prevo contends that even if the search were reasonable had she insisted on completing her mission of picking up the inmate, it became unreasonable once she asked to leave without her car being searched. This brings to mind our decision in
United States v. Herzbrun,
Any other result would not make sense at security chеck points in airports or in prison parking lots. We quoted in
Herz-brun
the explanation we had given in
Skip-with
for not allowing those carrying contraband to have a get-out-of-search-free card: “Such an option would constitute a one-way street for the benefit of a party planning airport mischief, since there is no guarantee that if he were allowed to leave he might not return and be more succеssful.”
Herzbrun,
That is essentially what Prevo wants. She urges us to follow the decision in
Gadson v. State,
Prevo informs us that the Alabama Department of Corrections has recently adopted a policy that states: “All vehicles are subject to be searched. If the driver refuses tо have the vehicle searched, [she] may be permanently restricted from visiting at any [Alabama Department of Corrections] institution.” Prevo reads into this new policy a right for a visitor to leave rather than have her car searched, but even assuming that her reading of it is a correct one, the revised policy was not in effect at the time Prevo’s car was searched. Even though it was not adopted until four-and-a-half years after the search in this case, Prevo argues that its existence still supports her position that the officers acted unconstitutionally in not permitting her to leave without a search. The core fault in- this argument is that the scope of the Fourth Amendment is not dependent on the willingness of the government to exercise its full powers. Nothing requires a governmental entity to exercise all the powers that it has, and timidity in exercising them does not shrink the scope of what is constitutionally permissible any more than boldness in exercising power expands the scope of it.
Finally, Prevo insists that even if the search is otherwise constitutionally permissible, it still violates the Fourth Amendment because the search program vested too much discretion in the officers conducting the search.
See, e.g., Delaware v. Prouse,
For these reasons, we conclude that the search of Prevo’s car was reasonable under the circumstances; it did not violate the Fourth Amendment. The judgment of conviction, which was conditioned on the correctness of the order denying the motion to suppress, is AFFIRMED.
