How come the patriot act is unconstitutional?

Critics argue that the USA PATRIOT Act is unconstitutional because it infringes on civil liberties and rights protected by the First and Fourth Amendments. Provisions such as broad surveillance powers and the ability to conduct searches without warrants are seen as violations of the right to privacy and protection against unreasonable searches. Additionally, the act has been criticized for its potential to undermine due process by expanding government authority without adequate oversight. These concerns highlight the tension between national security and individual freedoms.
