Which amendment is NOT a primary source of inmate rights?

The Ninth Amendment is often interpreted as a provision that protects rights not specifically enumerated in the Constitution. While it acknowledges that individuals may have additional rights beyond those explicitly stated, it does not directly address the rights of inmates or provide specific protections relevant to incarceration.

In contrast, the First Amendment protects freedoms concerning religion, expression, assembly, and the right to petition, all of which can relate to the rights of inmates, such as the freedom of speech and the right to practice one's religion. The Sixth Amendment provides rights related to criminal prosecutions, including the right to a fair trial and legal counsel, which are important for inmates involved in legal proceedings. The Eighth Amendment specifically prohibits cruel and unusual punishment, directly addressing the treatment of incarcerated individuals.

Thus, the Ninth Amendment does not serve as a primary source of inmate rights in the same way that the other amendments do.
