The United States Constitution has been amended 27 times since it was drafted in 1787. The first ten amendments, known as the Bill of Rights, were ratified in 1791 and include freedom of speech, the right to publish, practice religion, possess firearms, and assemble. The amendments were written by James Madison to limit government power and protect individual liberties. The Tenth Amendment, for example, specifies that any powers not explicitly granted to the federal government are reserved for the states or the people. The amendment process is challenging and time-consuming, requiring a two-thirds majority vote in both the House and the Senate or a constitutional convention called for by two-thirds of state legislatures.

Freedom of speech
The First Amendment to the US Constitution, which was passed by Congress on September 25, 1789, and ratified on December 15, 1791, is commonly recognized for its protection of freedom of speech, religion, the press, and the right to assemble and petition the government. The text of the amendment states:
> "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
The freedom of speech protected by the First Amendment has been interpreted by the Supreme Court to mean that no branch or section of the federal, state, or local governments can infringe upon any American's right to free speech. This interpretation has been extended to include modern forms of communication, such as the internet and television. However, it is important to note that private organizations, such as businesses and religious groups, are not bound by the same constitutional obligation to uphold freedom of speech.
The inclusion of freedom of speech in the First Amendment was influenced by the religious, political, and social elements of colonial America. By the time the United States declared independence in 1776, the Continental Congress agreed that a state-run church was antithetical to the freedoms they sought to establish. The Establishment Clause of the First Amendment thus prohibited the federal government from establishing an official religion, and state and local governments followed suit in the decades to come.
The Supreme Court has struggled at times to define the boundaries of protected speech under the First Amendment. For example, in Tinker v. Des Moines (1969), the Court ruled that students do not "shed their constitutional rights at the schoolhouse gate," upholding their right to wear black armbands to school to protest a war. Similarly, in Cohen v. California (1943), the Court found that the use of offensive words and phrases to convey political messages was protected speech.

Protection from unreasonable searches and seizures
The Fourth Amendment to the United States Constitution is part of the Bill of Rights. It protects the people from unreasonable searches and seizures by the government, specifically law enforcement officials. This amendment is a response to the Framers' experience of unjust searches and seizures under English rule.
The Fourth Amendment prohibits the federal and state governments from conducting unreasonable searches and seizures without a warrant. It requires that a warrant be issued by a judge or magistrate and justified by probable cause, supported by an oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized.
The Fourth Amendment does not protect against all searches and seizures, but only those deemed unreasonable under the law. The courts balance the degree of intrusion on an individual's rights and the legitimate interests of the government, such as public safety, to determine whether a search or seizure is reasonable.
The Fourth Amendment also applies to arrests and the collection of evidence. It has been interpreted to include conversation and protect against government intrusion into digital information, such as the contents of a cell phone.
In some cases, warrantless seizures of objects in plain view may not constitute a violation of the Fourth Amendment. However, warrantless searches and seizures are generally presumed to be unreasonable unless they fall within specific exceptions, such as exigent circumstances.

Powers reserved to the states
The Tenth Amendment to the US Constitution is a part of the Bill of Rights and was ratified in 1791. The purpose of the Tenth Amendment is to outline the balance of power between the federal government and the state governments, reserving powers to the states that are not specifically delegated to the federal government. This amendment ensures that all powers not granted to the federal government by the Constitution are reserved for the states or the people.
The amendment was introduced to address Anti-Federalist concerns during the Constitutional Convention of 1787. The Anti-Federalists feared that a strong federal government would infringe on states' rights and individual liberties. The Tenth Amendment was designed to allay these fears by explicitly stating that powers not granted to the federal government are reserved for the states or the people.
The amendment has been invoked in numerous Supreme Court cases to protect states' rights and limit federal power. For example, in the landmark case of United States v. Lopez (1995), the Court struck down a federal law that criminalized gun possession near schools, arguing that gun control was a matter for the states to decide. Similarly, in United States v. Morrison (2000), the Court ruled that parts of the Violence Against Women Act were unconstitutional because they exceeded the federal government's powers.
The Tenth Amendment continues to shape the interpretation of the Constitution today, with ongoing debates about the balance of power between the federal government and the states. It remains a crucial part of the US system of federalism, ensuring that states retain significant autonomy and that the federal government cannot usurp their powers.
