Airport Searches: Probable Cause Or Unreasonable Intrusion?

Airport security searches are a contentious issue, with many people questioning whether they violate an individual's rights. In the US, the Fourth Amendment protects individuals from unreasonable searches and seizures, and typically, a search warrant is required. However, there are exceptions to this rule, and airport searches are one of them. The government has a compelling reason to perform searches at airports due to security concerns, and passengers are generally required to consent to some level of search in order to ride on an airplane. While most TSA officers are not law enforcement officers, they do have the authority to search passengers and their belongings, even if there are no apparent security concerns. This has raised concerns about profiling and discriminatory behaviour, as TSA agents have wide discretion in selecting who to search.

The Fourth Amendment and airport searches

The Fourth Amendment of the United States Constitution protects individuals from unreasonable searches and seizures. Typically, a search warrant is required, but there are exceptions, such as when there is consent from the person being searched.

Airport Searches

Airplane passengers are subject to heightened scrutiny compared to the average law-abiding citizen. Every passenger must undergo some level of government search at the airport. This includes a search of their belongings and their person.

"For Cause" Searches

Some passengers are pulled aside for more thorough searches. These additional searches must be random or conducted for a specific security reason. These are known as "for cause searches". A search may be "for cause" for objective reasons, such as setting off a metal detector, or more subjective reasons, such as behaving in a "suspicious" manner.

Constitutional Concerns

Many airport searches are not authorized through the issuance of a search warrant following judicial scrutiny of the basis for suspicion. As such, they may involve constitutional infirmities. The Fourth Amendment protection against unreasonable searches applies only to government agencies. Therefore, for a constitutional problem to be posed by airport searches, government involvement must be present.

Exceptions

In Gold v. United States (1967), no constitutional infirmity was found in a search by airline personnel. However, if the government owns the airline's facilities, the airline may have to adhere to the constitutional standards that bind the government. The warrant requirement is also subject to exceptions with the consent of the searched person and during lawful arrests.

Border Inspections and Customs Searches

Typical airport searches are inconsistent with the probable cause requirements of statutes controlling border inspections and customs searches. Warrantless searches should be as limited as possible without frustrating legitimate state interests. This can be accomplished by conditioning baggage searches upon a positive indication from a magnetometer and a profile analysis.

Consent and search warrants

The Fourth Amendment of the United States Constitution protects individuals from unreasonable searches and seizures. Typically, a search warrant is required, however, there are several exceptions, including consent.

In the context of airport searches, the Fourth Amendment only applies to government agencies. In Gold v. United States (1967), no constitutional violation was found when an airline employee conducted a search. However, if the government owns the airline facilities, the airline may have to adhere to the constitutional standards that bind the government.

The warrant requirement is subject to exceptions with the consent of the searched person. However, this consent must be consent must be truly voluntary. For example, in

Random vs for cause searches

Airport security searches are a common occurrence, and most people are aware that they are subject to greater scrutiny than an average law-abiding citizen. While the Fourth Amendment of the United States Constitution protects individuals from unreasonable searches and seizures, it does not apply to airport searches in the same way. This is because, in the context of airport searches, individuals have a reduced "expectation of privacy". Additionally, passengers provide a level of consent to be searched as a condition of their privilege to ride on an airplane.

Random security checks at airports are a common procedure, and some travellers have reported being selected for these random checks. However, there is a concern that these random checks may be used as a cover for racial profiling and discriminatory behaviour. TSA agents have broad discretion in selecting individuals for additional screening, and they may base their decisions on subjective factors such as suspicious behaviour or a person's appearance.

On the other hand, "for cause" searches are conducted for specific security reasons. These searches may be triggered by objective factors such as setting off a metal detector or full-body scanner, or attempting to bring prohibited items on board. However, "for cause" searches can also be based on more subjective judgements made by TSA agents, such as deeming an individual's behaviour as suspicious.

While random searches may be truly random in some cases, there is evidence to suggest that racial profiling and subjective judgements play a role in selecting individuals for additional screening. This raises important questions about fairness and equality in airport security procedures.

Discrimination and profiling

Airport security checks have been a contentious issue since the September 11 attacks, with some critics arguing that they are discriminatory and infringe on civil liberties. Since 2001, there have been reports of increased racial profiling at airports, with people who appear to be Muslim or of Middle Eastern descent being targeted. This has led to accusations of ethnic witch-hunting and civil liberties infringement.

Some travellers have shared their experiences of being racially profiled while going through security. One person, Belal, a British citizen, reported that every time he travels from Berlin to his hometown of Nottingham, he is singled out and questioned about his reasons for visiting. Another traveller, Karim, shared that he was pulled aside for additional searches at the gate, which included a pat-down and swabbing of electronic items for explosives. He also noticed that most of the names on the list for extra searches seemed to be "foreign-sounding".

Uzair, a parliamentary researcher to the shadow secretary of state for business innovation and skills, was the only non-white passenger on a flight from Belfast to Manchester and was selected for further questioning. He was allowed to leave after declaring his occupation, but not before being embarrassed in front of the other passengers.

Abbas, a mixed-race person, was pulled out of the check-in queue at London Heathrow and questioned about travelling alone. On the way back to the UK, he was held for several hours in a room with only Mexican nationals, alluding to profiling based on ethnic background.

Katie, another mixed-race traveller, shared that she receives extra pat-downs and is often called to the side when boarding flights. She has come to expect these extra checks and is now pleasantly surprised when they don't happen.

While some view passenger profiling as a necessary security measure, others argue that it is an invasion of privacy and a potential violation of constitutional rights. The Fourth Amendment of the United States Constitution protects individuals from unreasonable searches and seizures, and typically, a search warrant is required. However, airports are an exception, and passengers are subject to heightened scrutiny. The wide latitude given to TSA agents in conducting searches, including "random" searches, raises concerns about profiling and discriminatory behaviour.

To address these concerns, some suggest improving training programs for security personnel to broaden their scope beyond focusing solely on the Islamist threat to aviation. Active engagement through short, unscripted conversations with travellers is proposed as a more effective way to conduct security checks.

Full-body scanner searches

Full-body scanners are devices that detect objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact. They can detect non-metal objects, as well as items swallowed or hidden in body cavities.

There are three distinct technologies used in full-body scanners:

• Millimeter wave scanners use non-ionizing electromagnetic radiation in the extremely high-frequency radio band. The health risks posed by these machines are still being studied, and evidence is mixed.
• Backscatter X-ray scanners use low-dose radiation to detect suspicious metallic and non-metallic objects hidden under clothing or in shoes and body cavities. This type of scanner has sparked considerable debate about safety, leading multiple countries to ban them.
• Transmission X-ray scanners use higher doses of penetrating radiation to detect objects hidden under clothes or inside the body. The dosage received is usually not higher than 0.25 μSv and is regulated by the American radiation safety standard for personal search systems.

Full-body scanners have been criticised by passengers and advocates for displaying naked body images to screening agents and recording them. Critics have called this a virtual strip search without probable cause, claiming that it is illegal and violates basic human rights. In response to these concerns, the Transportation Security Administration (TSA) has implemented measures to ensure passenger privacy, such as blurring face images, installing software to make images less provocative, and separating security personnel from passengers.

The use of full-body scanners in airports has been the subject of legal challenges. In the United States, the Electronic Privacy Information Center (EPIC) filed a lawsuit in 2010, arguing that the scanners violated the Fourth Amendment, the Privacy Act, the Religious Freedom Restoration Act, and the Video Voyeurism Prevention Act. In 2011, the United States Court of Appeals ruled that the use of full-body scanners at airport security did not violate the Fourth Amendment.

Despite the controversy and legal challenges, full-body scanners have become a standard security measure in airports worldwide due to concerns about terrorism and the smuggling of prohibited items. However, there are ongoing efforts to improve the technology to address privacy and health concerns.
