Us Teargassing Mexico: Legal Or Not?

In November 2018, U.S. authorities shut the country's busiest border crossing and fired tear gas into Mexico to prevent a group of Central American migrants from crossing over from Tijuana. This incident, along with another in January 2019, sparked outrage and raised questions about the legality of using tear gas in such a manner. While the U.S. government has defended its actions, legal and rights experts have questioned whether the use of force was justifiable and legal, especially considering the presence of children in the crowd. This incident has brought to light the lack of specific regulations and safety studies regarding the use of tear gas by law enforcement in the U.S.

The legality of firing tear gas into another country

Firing tear gas into another country is a highly controversial issue. While there are no explicit international laws prohibiting the use of tear gas in cross-border incidents, it may violate the territorial integrity and sovereignty of the target country. Additionally, the use of tear gas itself is contentious, as it can cause severe harm and violate human rights, especially when used against vulnerable populations.

International Law and Treaties

According to Geoff Gilbert, a professor of international human rights and humanitarian law, while countries have the right to control their borders and maintain order, firing tear gas into another country may violate the territorial integrity clause in Article 2 of the United Nations Charter. This article states that members shall refrain from the "threat or use of force against the territorial integrity" of other nations.

Furthermore, the use of tear gas in warfare is prohibited under the Chemical Weapons Convention, which has been signed by most countries. However, a compromise was reached during the drafting process, allowing the use of tear gas for law enforcement purposes. This exemption has been highly controversial and criticized by human rights organizations.

Human Rights Concerns

The use of tear gas, particularly against vulnerable populations, raises serious human rights concerns. Tear gas is inherently indiscriminate and can cause severe injuries and even death. It cannot distinguish between different types of individuals, such as the young, elderly, healthy, or sick. Its deployment can result in excessive force and violate the principle of proportionality, as outlined in international human rights law.

Examples of Cross-Border Tear Gas Incidents

There have been several notable incidents of tear gas being fired across international borders:

• U.S. Border Patrol agents fired tear gas into Mexico on multiple occasions, including in November 2018 and January 2019, to deter migrants from crossing the border. These incidents sparked outrage and calls for investigations, with critics arguing that the use of tear gas was disproportionate and violated Mexico's sovereignty.
• In 2015, Hungary was widely criticized for tear-gassing migrants and refugees in Serbia who were seeking to enter the country.

While there is no explicit international law prohibiting the firing of tear gas into another country, it raises complex legal and ethical issues. The use of tear gas itself is contentious, and when fired across borders, it can violate the sovereignty and territorial integrity of the target nation. Additionally, the indiscriminate nature of tear gas and its potential to cause harm and violate human rights further complicates its use in cross-border contexts.

The legality of using tear gas on asylum seekers

The use of tear gas on asylum seekers has been a highly controversial issue, with incidents of US border agents firing tear gas into Mexico to deter migrants from crossing the border. While the US government has defended these actions as necessary to protect its borders and its agents, the legality of using tear gas in this manner is questionable.

International law and treaties, such as the United Nations Charter and the Chemical Weapons Convention, provide some guidance on the use of force and chemical weapons. According to the Chemical Weapons Convention, tear gas is banned in armed conflict but permitted for domestic law enforcement purposes. However, the use of tear gas across an international border against asylum seekers does not clearly fall into either the banned or permitted purposes outlined in the treaty.

Legal experts argue that countries have the right to control their borders and protect their territories, but this does not give them the right to fire tear gas into another country's territory. Article 2 of the United Nations Charter states that members "shall refrain in their international relations from the threat or use of force against the territorial integrity" of other members. This suggests that the use of tear gas across the US-Mexico border may violate international law.

Human rights groups and activists have also raised concerns about the use of tear gas on vulnerable groups, including women and children. They argue that the use of tear gas in this context could violate international human rights standards and cause additional harm, panic, injury, and even death. The impact of tear gas on individuals can be severe, causing eye pain, coughing, burning sensations in the throat and nose, and in some cases, temporary vision loss.

Furthermore, the use of tear gas on asylum seekers may subvert the rights of this special class of individuals. Under Article 14 of the Universal Declaration of Human Rights, "everyone has the right to seek and to enjoy in other countries asylum from persecution." Restricting access to asylum seekers or using excessive force to deter them may violate international law, as Amnesty International has claimed in response to the US government's actions.

While the legality of firing tear gas into Mexico to deter asylum seekers is ambiguous, the immorality and potential for human rights violations are undeniable. The United States has faced widespread criticism and calls for investigations into these incidents, highlighting the complex nature of border security and the importance of upholding humanitarian principles.

The legality of using tear gas on children

International Law and Border Issues

The use of tear gas across international borders is particularly contentious. Geoff Gilbert, a professor of international human rights and humanitarian law, asserts that while countries have the right to control their borders, this does not give them the right to fire tear gas into another country's territory. This act may violate the United Nations Charter, which states that members shall "refrain in their international relations from the threat or use of force against the territorial integrity" of other members.

Human Rights Concerns

Rights experts and activists have expressed concern over the use of tear gas on vulnerable groups, including children. They argue that the indiscriminate nature of tear gas dispersal can cause harm, panic, injury, and even death. The use of tear gas in these contexts may violate international human rights standards, particularly when it is deemed a disproportionate use of force.

Proportionality and Necessity

The principle of proportionality dictates that the force used must be proportional to the seriousness of the threat. In situations involving children, who are inherently vulnerable, the use of tear gas may be considered disproportionate unless there is an imminent and significant threat.

Health Risks and Lack of Research

There is limited research on the health effects of tear gas, particularly on vulnerable populations such as children. However, exposure to tear gas can cause severe eye and respiratory pain, skin irritation, bleeding, and even blindness. The short and long-term effects of tear gas exposure can be detrimental, and people with pre-existing respiratory conditions are especially at risk of developing respiratory illnesses and other complications.

Domestic Law and Guidelines

In summary, the legality of using tear gas on children is a complex issue involving international law, human rights considerations, health risks, and domestic regulations. While the use of tear gas for riot control is generally permitted, its deployment across international borders and against vulnerable groups, including children, raises serious legal and ethical concerns. Further regulations and research are needed to ensure the protection of children's rights and well-being in these contexts.

The legality of using tear gas domestically

The use of tear gas, also known as a lachrymatory agent, is banned in warfare by various international treaties, including the Geneva Protocol of 1925 and the Chemical Weapons Convention. However, its domestic use by law enforcement and military personnel for riot control is not prohibited in the same manner. While tear gas is considered legal for police and federal authorities to use domestically in riot-control situations, its legality is questionable when fired across international borders.

International law considerations

The United Nations Charter, for example, states that members "shall refrain in their international relations from the threat or use of force against the territorial integrity" of other members. Firing tear gas across an international border can be seen as a violation of another country's territory and an interference in its internal affairs.

Human rights concerns

The use of tear gas in the context of international human rights law is also problematic. Tear gas is inherently indiscriminate and can cause severe eye and respiratory pain, skin irritation, bleeding, and even blindness. Its use against vulnerable populations, such as women, children, and asylum seekers, raises serious concerns.

Domestic law considerations

In the United States, for instance, the use of tear gas by law enforcement is governed by guidelines that permit its use in situations where "less-lethal force" is necessary to control "disorderly or violent subjects". However, these guidelines are open to interpretation and do not always align with the principles of necessity and proportionality that should govern the use of force by law enforcement authorities.

Calls for a ban on tear gas

There have been increasing calls for a complete ban on the use, trade, and manufacture of tear gas. Some countries and jurisdictions have already banned its export and use by police forces domestically. Additionally, international rights groups, as well as the UN and EU, are working to restrict the use and trade of tear gas.

The legality of using tear gas in warfare

The use of tear gas in warfare is a highly controversial issue that has been the subject of much debate and condemnation. While some argue that it is banned under international treaties on chemical weapons, others claim that it is permissible under certain circumstances. So, what is the legality of using tear gas in warfare?

International Law and Treaties

According to the 1925 Geneva Protocol, the use of "asphyxiating, poisonous or other gases, and of all analogous liquids, materials or devices" as well as "bacteriological methods of warfare" is prohibited. This agreement, ratified by the United States in 1975, banned the use of chemical and biological weapons in warfare but did not specifically mention tear gas. Additionally, the 1993 Chemical Weapons Convention, which the United States signed and ratified, banned the use of riot control agents (RCAs), including tear gas, as a "method of warfare." However, it is important to note that the CWC does not define the term "method of warfare," leaving room for interpretation.

United States Position

The United States has consistently maintained that the Geneva Protocol does not apply to tear gas. The domestic legal regime in the US preserves the option to employ RCAs under specific circumstances. For example, Executive Order 11850 prohibits the use of RCAs "in war" but allows exceptions for "defensive military modes to save lives" when approved by the President. This order does not define "defensive military modes" but provides examples such as rear-area and prisoner riot control and situations involving civilians used as human shields.

Criticism and Condemnation

The use of tear gas by American border protection agents has been widely criticized and condemned. In November 2018, US agents fired tear gas at migrants attempting to cross the Mexico-US border, resulting in international outrage and calls for investigation from the Mexican government. Similar incidents have occurred multiple times since then, with agents firing tear gas into Mexico to deter migrants from crossing the border. These actions have been described as a "violation of international human rights standards" and a "disproportionate use of force."

In conclusion, the legality of using tear gas in warfare is a complex and contentious issue. While international treaties ban the use of chemical weapons, including tear gas, there are exceptions and loopholes that allow for its use in certain circumstances. The interpretation of these treaties and the justifications for using tear gas vary, and the consequences of its use can be severe. Therefore, the decision to employ tear gas should be made with careful consideration of the legal, ethical, and humanitarian implications.
